Amplify Force and Motion, Chapters 1 and 2

Front

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

Back

A force is required to cause an object to change its velocity.

Front

What is the force applied to an object as it moves across a surface called?

Back

The force applied to an object as it moves across a surface is called friction.

Front

If two objects of different masses have the same force applied, which will have a greater change in velocity?

Back

The less massive object will have a greater change in velocity.

Front

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

Back

A force must be applied in the opposite direction of velocity to cause an object to slow down.

Front

What can understanding a cause and effect relationship help you do?

Back

Understanding a cause and effect relationship can help you infer what led to a particular result.

Front

What is the definition of force?

Back

Force is a push or pull on an object that can cause it to change its velocity.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object as it moves across a surface.

Front

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

Back

When a net force is applied to an object, its velocity changes.

Front

What is the relationship between mass and acceleration when a constant force is applied?

Back

The greater the mass of an object, the less acceleration it will have when a constant force is applied.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
