Amplify Force and Motion, Chapters 1 and 2

Front

What are the five ways an object's motion can change?

Back

start, stop, change direction, speed up, slow down

Front

What is required to cause an object to change its velocity?

Back

A force

Front

In order to cause an object to slow down, in which direction must a force be applied?

Back

Opposite direction of velocity

Front

How does the direction of the force affect an object's velocity?

Back

It determines how the velocity changes.

Front

What is velocity?

Back

The speed of an object in a particular direction.

Front

What is the relationship between force and motion?

Back

Force is necessary to change an object's motion.

Front

What happens to an object's motion when a net force is applied?

Back

The object's motion will change according to the direction and magnitude of the net force.

Front

What is the effect of balanced forces on an object's motion?

Back

Balanced forces do not change an object's motion.

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

How can an object accelerate if no net force is acting on it?

Back

An object cannot accelerate without a net force acting on it.
