A device that changes the direction or the amount of effort needed to do work.
-
Acceleration
-
Force
-
Machine
Correct Answer
A. MachineExplanation
A machine is a device that can change the direction or the amount of effort needed to do work. It can be a mechanical or electronic device that is designed to perform specific tasks or functions. Machines can be simple, like a lever or a pulley, or complex, like a computer or a car. They are used to make work easier by reducing the amount of force required or by changing the direction of the force. Machines are an essential part of our daily lives and are used in various industries and fields.Rate this question:

the speed and direction of an objects motion
-
Acceleration
-
Velocity
-
Inerta
Correct Answer
A. VelocityExplanation
Velocity is the correct answer because it refers to both the speed and direction of an object's motion. While acceleration also relates to changes in an object's motion, it specifically refers to changes in velocity over time. Inertia, on the other hand, is the tendency of an object to resist changes in its state of motion.Rate this question:

Machine
Correct Answer
A. ForceExplanation
Force is defined as a push or pull that acts on an object. It is a physical quantity that can cause an object to accelerate, decelerate, or change direction. Force is measured in units called Newtons and can be exerted through direct contact or at a distance. It is a fundamental concept in physics and is responsible for the motion and interaction of objects in the universe.Rate this question:

Work
Correct Answer
A. WorkExplanation
Work is the energy used when a force is applied to move an object. It is the product of the force applied and the distance over which the force is applied. Work is done when there is a displacement of the object in the direction of the force applied. It is a measure of the transfer of energy from one object to another. Therefore, work is the correct answer in this context as it represents the energy used when a force moves an object.Rate this question:

The rate at which work is done
-
Power
-
Force
-
Speed
Correct Answer
A. PowerExplanation
Power is the correct answer because it is defined as the rate at which work is done. It measures how quickly work is being performed or how much energy is transferred per unit time. Power is calculated by dividing the amount of work done by the time it takes to do that work. Therefore, power is directly related to the rate at which work is done. Force and speed are not equivalent to power as they do not take into account the time factor.Rate this question:

Velcity
-
Equilibrium
Correct Answer
A. EquilibriumExplanation
Equilibrium refers to a state in which the net force acting on an object is zero. This means that the forces acting in opposite directions are balanced, resulting in no acceleration or change in motion. In this state, the object can be at rest or moving at a constant velocity. Thus, equilibrium is the correct answer as it accurately describes the state where the net force is zero.Rate this question:

the rate at which the velcoity of an object changes over time
-
Acceleration
-
Average speed
-
Velocity
Correct Answer
A. AccelerationExplanation
Acceleration refers to the rate at which the velocity of an object changes over time. It measures how quickly an object's speed or direction changes. If an object's velocity is increasing, it is said to have positive acceleration, while if it is decreasing, it has negative acceleration. Average speed, on the other hand, is the total distance traveled divided by the total time taken, and velocity is the rate at which an object's position changes in a specific direction. Therefore, acceleration is the correct answer as it specifically relates to the change in velocity over time.Rate this question:
