Play this quiz, give answers to the questions and review your knowledge regarding work and energy. For work to take place, an amount of energy has to be used. Work can either change the kinetic energy or change the potential energy. Do you understand the connection between work and energy? Test how well you understood these two topics by taking the quiz below. All the best, and keep looking for more tests on the topic.

• 1.

### What is the formula for work?

• A.

Force x Distance

• B.

Distance/Force

• C.

Force/Distance

• D.

None

A. Force x Distance
Explanation
The formula for work is force multiplied by distance. This means that in order to calculate the amount of work done, you need to multiply the force applied to an object by the distance over which the force is applied. This formula is derived from the definition of work as the transfer of energy that occurs when a force is applied to an object and it moves in the direction of the force.

Rate this question:

• 2.

### What is the relationship between Work, Force, and Distance?

• A.

Work is what you get when a force acts over a certain distance. Therefore, without distance or force there would be no work.

• B.

Work and Distance are related because force is acted over a long distance.

• C.

Without work you do not have force.

• D.

All are true about work, force, and distance.

A. Work is what you get when a force acts over a certain distance. Therefore, without distance or force there would be no work.
Explanation
The relationship between Work, Force, and Distance is that work is the result of a force acting over a certain distance. Without either distance or force, there would be no work. This explanation accurately summarizes the relationship between these three concepts.

Rate this question:

• 3.

### What are the units for work?

• A.

Watts

• B.

Dollars

• C.

Joules

• D.

Meters

C. Joules
Explanation
The units for work in the International System of Units (SI) are joules (J). However, work can also be expressed in other units depending on the context, such as foot-pounds (ft-lb) or ergs (erg) in different systems of measurement.

Rate this question:

• 4.

### If you exert a force of 800 newtons, and the object moves 10 meters how much work did you do?

• A.

8000 Joules

• B.

80 Joules

• C.

80,000 Joules

• D.

800 Joules

A. 8000 Joules
Explanation
When you exert a force of 800 newtons and the object moves 10 meters, the work done can be calculated using the formula: work = force Ã— distance. Plugging in the given values, we get work = 800 newtons Ã— 10 meters = 8000 Joules. Therefore, the correct answer is 8000 Joules.

Rate this question:

• 5.

### What is energy, and how does it relate to work?

• A.

Energy is the ability to do work or make work, and without it work not is done.

• B.

Energy causes a change, and work is needed for energy to happen.

• C.

Energy is the ability to do work or cause a change, and work is the transfer of energy.

• D.

C. Energy is the ability to do work or cause a change, and work is the transfer of energy.
Explanation
This statement accurately describes the relationship between energy and work. Energy is the capacity to do work, and work involves the transfer of energy to accomplish a task or cause a change in a system. Therefore, work and energy are closely related concepts in physics.

• 6.

### What is the unit of measurement for energy?

• A.

Watts

• B.

Joules

• C.

Newtons

• D.

Kilowatt

B. Joules
Explanation
The unit of measurement for energy is joules. This is a derived unit in the International System of Units (SI) and is used to measure various forms of energy such as mechanical, thermal, and electrical energy. Watts, on the other hand, are used to measure power, which is the rate at which energy is transferred or converted. Newtons are used to measure force, and kilowatts are a unit of power equal to 1000 watts.

Rate this question:

• 7.

### What are the differences between Kinetic and Potential energy?

• A.

Kinetic energy is the energy of motion, and potential energy is stored energy

• B.

Potential energy is the energy of weight, and kinetic energy is the energy of nuclear atoms.

• C.

Potential energy is the energy of speed, and kinetic energy is the stored energy.

• D.

There is no difference between the two.

A. Kinetic energy is the energy of motion, and potential energy is stored energy
Explanation
Kinetic energy refers to the energy possessed by an object due to its motion. It is directly proportional to the mass and velocity of the object. On the other hand, potential energy is the energy that an object possesses due to its position or state. It is stored energy that can be converted into kinetic energy. Examples of potential energy include gravitational potential energy, elastic potential energy, and chemical potential energy. Therefore, the given answer correctly explains that kinetic energy is associated with motion, while potential energy refers to stored energy.

Rate this question:

• 8.

### Examples of Potential Energy are?

• A.

Gravielastic energy, and Joules

• B.

Gravitational potential energy which is dependent on the height of the object.

• C.

Nucleus potential energy, depending on the amount of nuclear power.

• D.

A person walking

B. Gravitational potential energy which is dependent on the height of the object.
Explanation
Gravitational potential energy is a type of potential energy that depends on the height of an object. When an object is lifted to a higher position, it gains potential energy due to the force of gravity acting on it. This potential energy can be converted into other forms of energy, such as kinetic energy, when the object falls or is released. Therefore, gravitational potential energy is a clear example of potential energy. The other options mentioned in the question, such as gravielastic energy, Joules, nucleus potential energy, and a person walking, are not examples of potential energy or do not provide enough information to be considered as potential energy examples.

### What is the formula for G.P.E, and do a calculation?

• A.

GPE= 1/2 Mass X Velocity 10kg x 54m/s = 540 540/2= 270

• B.

GPE= M x G x H 5kg x 10x 2m = 100 Joules

• C.

GPE= M x G x H 5kg x 10x 2m = 100 Watts

• D.

None

B. GPE= M x G x H 5kg x 10x 2m = 100 Joules
Explanation
The formula for gravitational potential energy (GPE) is given by GPE = M x G x H, where M represents the mass, G represents the acceleration due to gravity, and H represents the height. In this case, the mass is 5kg, the acceleration due to gravity is 10m/s^2, and the height is 2m. By substituting these values into the formula, we can calculate the GPE as 100 Joules.

Rate this question:

• 10.

### What is the difference between Elastic Potential Energy and GPE?

• A.

GPE is potential energy that's dependent on height, EPE is energy associated with objects that can be stretched or compressed

• B.

GPE is potential energy dependent on weight only, and EPE is the potential energy only found in rubber bands.

• C.

GPE and EPE are the same, but are not written the same way.

• D.

Both are same as there is no difference between the two.

A. GPE is potential energy that's dependent on height, EPE is energy associated with objects that can be stretched or compressed
Explanation
The correct answer is that GPE is potential energy that is dependent on height, while EPE is energy associated with objects that can be stretched or compressed. This means that GPE is related to the vertical position or height of an object, while EPE is related to the deformation or stretching/compression of an object.

Rate this question:

• 11.

### What is the formula for Kinetic Energy?

• A.

1/2 Mass x Velocity squared

• B.

Mass x Velocity x 2

• C.

Velocity / Mass x 1/2

• D.

Mass x Velocity

A. 1/2 Mass x Velocity squared
Explanation
The formula for kinetic energy is 1/2 Mass x Velocity squared. This formula calculates the amount of energy an object possesses due to its motion. The kinetic energy is directly proportional to the mass of the object and the square of its velocity. Therefore, increasing either the mass or the velocity of an object will result in a higher kinetic energy.

Rate this question:

• 12.

### When is there more GPE in a swinging pendulum?

• A.

At the top

• B.

At its lowest point

• C.

In between the top, and the lowest point

• D.

At the bottom

A. At the top
Explanation
At the top of a swinging pendulum, there is more gravitational potential energy (GPE) because the height is at its maximum. As the pendulum swings downward, the height decreases, resulting in a decrease in GPE. At the lowest point, the height is minimum, and therefore the GPE is also minimum. In between the top and the lowest point, the GPE continuously decreases as the height decreases. At the bottom, the GPE is the lowest because the height is zero.
