• direction and speed

• speed and energy

• volume and direction

What kind of energy do all moving objects have?

• kinetic energy

• potential energy

• renewable energy

• solar energy

Which would be an example of kinetic energy?

• child sitting in a chair

• book resting on a shelf

• car waiting in a parking spot

• man climbing a ladder

A force can be described as:

• direction or speed

• push or pull

• motion or mass

• mass or speed

Which term refers to the combination of all forces acting on an object?

• speed

• motion

• direction

• net force

An object with zero net force will...

• change its direction

• increase its speed

• stay at rest

• increase its friction

Unless acted on by a force, objects in motion tend to stay in ________.

• motion
• rest

• force

• friction

With objects of the same mass, the greater the force, the greater the change in ________.

• friction

• mass

• motion

• force

Which term refers to the force that opposes the motion of an object?

• speed

• net force

• friction

• motion

More friction will make an object:
