Newton's Laws of Motion

Front

What is the tendency of a physical object to remain still or continue moving, unless force is applied?

Back

Inertia

Front

What law states that acceleration of an object depends on the object's mass and the magnitude of the force acting upon it (F=ma)?

Back

Newton's Second Law of Motion

Front

What is the term for the resistance or force of equal magnitude acting in the opposite direction to an action force?

Back

Reaction

Front

What law states that an object at rest stays at rest or an object in motion stays in motion until unbalanced forces act upon it?

Back

Newton's First Law of Motion

Front

What term describes the way that something causes a change?

Back

Action

Front

What is the relationship between force, mass, and acceleration as described by Newton's Second Law?

Back

F = ma (Force equals mass times acceleration)

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the object's motion.

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause a change in the object's motion.

Front

What is an example of inertia in everyday life?

Back

A passenger lurching forward in a car when it suddenly stops.

Front

What does Newton's Third Law of Motion state?

Back

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