Force & Motion

When a roller coaster moves down a ramp

• kinetic energy changes to potential energy
• electrical energy changes to light energy
• potential energy changes to kinetic energy
• gravity is not involved

The tendency of an object to stay in motion or at rest is called 

• velocity
• acceleration
• speed
• inertia

Which of the following describes energy?

• the ability to remain in motion
• the ability to do work
• the ability to pull objects down
• the ability to change states

When a ball rolls down a hill 

• kinetic energy is created
• potential energy is created
• thermal energy is created
• none of these

Work involves all of these except 

• force
• movement
• distance
• time

If bricks are loaded into an empty wheelbarrow, which of these is true?

• less force is needed to move the wheelbarrow
• the amount of friction increases
• more force is needed to move the wheelbarrow
• the wheelbarrow's speed increases

All of these affect inertia except 

• size
• mass
• shape
• color
