What is Newtons first law?

a)

Force equals mass times acceleration.

b)

An object in motion tends to stay in motion and objects at rest tend to stay at rest unless acted upon by an unbalanced force.

c)

For every action, there is an equal and opposite reaction.

d)

change in position of an object over time.

2.

What is Newtons second law?

a)

Force equals mass times acceleration.

b)

the strength and vitality required for sustained physical or mental activity.

c)

An object in motion tends to stay in motion and objects at rest tend to stay at rest unless acted upon by an unbalanced force.

d)

For every action, there is an equal and opposite reaction.

3.

What is Newtons third law?

a)

Force equals mass times acceleration.

b)

For every action, there is an equal and opposite reaction.

c)

Power = Work/Time

d)

An object in motion tends to stay in motion and objects at rest tend to stay at rest unless acted upon by an unbalanced force.

4.

What is mechanical energy?

a)

sum of kinetic and potential energy in an object that is used to do work. It is also energy in an object due to its motion or position.

b)

change in position of an object over time.

c)

An object in motion tends to stay in motion and objects at rest tend to stay at rest unless acted upon by an unbalanced force.

d)

rate at which work is done

5.

What is work?

a)

a body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing.

b)

a coherent, typically large body of matter with no definite shape.

c)

any interaction that, when unopposed, will change the motion of an object.

d)

there is a displacement of point of the application in the direction of the force.

6.

What is weight?

a)

a body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing.

b)

a coherent, typically large body of matter with no definite shape.

c)

any interaction that, when unopposed, will change the motion of an object.

d)

there is a displacement of point of the application in the direction of the force.

7.
