newton's laws quiz review grade 8

Which of Newton's Laws is demonstrated by a ball rolling to a wall then stopping?

• Newton's First Law

• Newton's Second Law

• Newton's Third Law

• None of the above

What is the First Law of Motion

• Acceleration depends on the object's mass and on the net force acting on the object

• If one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object

• An object at rest will remain at rest, and an object moving at a constant velocity will continue moving at a constant velocity, unless it is acted upon by an unbalanced force

• none of the above

What is the Second Law of Motion?

• Acceleration depends on the object's mass and on the net force acting on the object

• An object at rest will remain at rest, and an object moving at a constant velocity will continue moving at a constant velocity, unless it is acted upon by an unbalanced force

• If one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object

• none of the above
