BJU Science 6 Laws of motion

What is motion?

• When an object stops

• When an object changes position

• When an object is at rest

What is the name given to an object that is fixed when you are determining whether an object is in motion?

• object

• moving object

• reference point

What is resistance to a change in motion called?

• inertia

• mass

• force

• acceleration

Which law of motion says an object at rest stays at rest, and an object in motion stays in motion?

• Newton's first law of motion

• Newton's second law of motion

• Newton's third law of motion

• Newton's forth law of motion

Which of Newton's laws of motion say that for every force exerted there is an equal force exerted back of "action and reaction"?

• Newton's first law of motion

• Newton's second law of motion

• Newton's third law of motion

• Newton's forth law of motion

In Newton's Second law of motion what two things increase or decrease force
