Newton's Second Law of Motion

Front

What happens when an object speeds up, slows down, or changes direction?

Back

It accelerates.

Front

When does acceleration occur?

Back

Whenever an unbalanced force acts on an object.

OR

When an object's motion changes.

Front

What two factors affect the acceleration of an object?

Back

The net force acting on the object and the object’s mass.

Front

What does Newton’s second law of motion describe?

Back

How force and mass affect acceleration.

Front

State Newton’s second law of motion.

Back

The acceleration of an object equals the net force acting on the object divided by the object’s mass.

Front

What is the relationship between force and acceleration according to Newton’s second law?

Back

There is a direct relationship between force and acceleration.

Front

What happens to acceleration if the force on an object is doubled?

Back

Doubling the force on the object doubles its acceleration.

Front

What is the relationship between mass and acceleration?

Back

It is an inverse relationship.

Front

What happens to acceleration if the mass of an object is doubled?

Back

Doubling the mass of an object results in only half as much acceleration for the same amount of force.
