Amplify Force and Motion Chapter 1

Front

What direction must a force act in for an object to speed up?

Back

The force must act in the same direction as the object's motion.

Front

What type of force causes an object to travel faster?

Back

The stronger force.

Front

What is the effect of friction on a moving object?

Back

Friction slows down the object.

Front

From which direction must a force come to start moving an object?

Back

The force can come from any direction.

Front

What is speed in a particular direction called?

Back

Velocity.

Front

What is the definition of force?

Back

A push or pull that can change the motion of an object.

Front

What happens to an object's motion when a net force acts on it?

Back

The object will accelerate in the direction of the net force.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

How does mass affect the motion of an object?

Back

More mass means more force is needed to change its motion.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, Force = Mass x Acceleration.
