Potential & Kinetic Energy - Quiz 1

Which is the best example of an object with only potential energy?

• A boat moving through the water.

• A boulder resting on top of a cliff.

• A ball being thrown across a field.

• Water being poured out of a pitcher.

Which of the following best represents potential energy?

• Air leaking rapidly from a car tire.

• A marble sitting at the top of a ramp.

• Heat radiating from a large forest fire.

• Water flowing through a rubber hose.

As a boulder rolls from the top of a hill to the bottom, how does its potential and kinetic energy change?

• Potential and kinetic energy both increase.

• Potential increases and kinetic decreases.

• Potential decreases and kinetic increases.

• Potential and kinetic energy both decrease.

Which of these best shows a change from potential to kinetic energy?

• Water flowing over a tall cliff.

• A rubber band being stretched.

• Electricity making a bulb light up.

• A stone lying on top of a mountain.

A truck is parked at the bottom of a hill. It moves from the bottom of a hill and parks at the top. Compared to when it was parked at the bottom of the hill at its new position, the truck now has –

• more potential energy.

• more kinetic energy.

• less potential energy.

• less kinetic energy.

The illustration shows a rollercoaster and indicates four different positions the car might be at as it moves along the track.

At which point in the rollercoaster’s journey is its potential energy the greatest?

• W

• X

• Y

• Z

Potential energy and kinetic energy are similar in that both –

• are demonstrated when an object is at rest.

• depend on the height of an object above the ground.

• can each be converted into the other form.

• will produce an increase in the mass of an object.

At which position does the pendulum have the most kinetic energy?

• 1

• 2

• 3

• 1 & 5
