Unit 15 Forces and Motion

What is a force that causes a change in motion?

What is a force attraction between two objects, even if they are not touching?

What is the tendency of objects to resist a change in motion?

What is a push or a pull, which causes movement or change in an object's movement or shape?

What is a force on an object that is equal in size and opposite in direction?

What is a force that opposes motion and acts between two objects that are touching?

An object is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. Which law is this?

• Newton's Second Law of Motion

• Newton's Third Law of Motion

• Newton's First Law of Motion

Which of Newton's laws states: An objects acceleration depends on two factors-the amount of force applied to the object and the object's mass.

• Newton's First Law of Motion

• Newton's Second Law of Motion

• Newton's Third Law of Motion

Which of Newton's Laws states: for every action (force) in nature there is an equal and opposite reaction. If object A exerts a force on object B, object B also exerts an equal and opposite force on object A.

• Newton's First Law of Motion

• Newton's Second Law of Motion

• Newton's Third Law of Motion

Why do Newton's laws of motion apply to objects in space?
