Multiple Choice

Which of the following statements about kinetic energy is correct?

• Kinetic energy only makes objects move from place to place.

• Kinetic energy is only found in large objects like planets.

• Kinetic energy makes objects vibrate, rotate, and move from place to place.

• Kinetic energy is not found in atoms.

Open Ended

Explain how kinetic energy can be transferred or transformed, using examples from everyday life.

Multiple Choice

What is the formula for calculating kinetic energy, and how does changing speed affect the kinetic energy of an object?

Multiple Choice

If an athlete doubles their mass but keeps the same speed, what happens to their kinetic energy?

• It stays the same.

• It is cut in half.

• It doubles.

• It quadruples.

Multiple Choice

Which factor has a greater effect on kinetic energy: changing speed or changing mass?

• Changing speed

• Changing mass

• Both have equal effect

• Neither affects kinetic energy

Open Ended

Explain how you would use the kinetic energy formula to find the speed of an object if you know its mass and kinetic energy.

Multiple Choice

If an object is not moving relative to its reference point, what is its kinetic energy?

• Zero

• Maximum

• Depends on mass

• Depends on speed

Multiple Select

Which of the following statements about kinetic energy and reference points are correct?

• Kinetic energy is measured relative to a reference point.

• If an object is not moving relative to the reference point, it has no kinetic energy.

• Kinetic energy does not depend on the reference point.

• An object always has kinetic energy regardless of reference point.

Multiple Choice

If a car's speed doubles, what happens to its kinetic energy and braking distance?

• Both kinetic energy and braking distance double.

• Kinetic energy doubles, braking distance quadruples.

• Both kinetic energy and braking distance quadruple.

• Kinetic energy quadruples, braking distance doubles.

Open Ended
