Questions and Answers

- 1.What is the formula for work?
- A.
Force x Distance

- B.
Distance/Force

- C.
Force/Distance

- 2.What is the relationship between Work, Force, and Distance?
- A.
Work is the 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.

- 3.What are the units for work?
- A.
Watts, and Joules

- B.
Dollars, and Euros

- C.
Newton Meter, and Joules

- 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

- 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.

- 6.What is the unit of measurement for energy?
- A.
Watts

- B.
Joules

- C.
Newtons

- 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.

- 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.

- 9.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

- 10.
- 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.

- 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

- 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
