Kinetic and Potential Energy Quiz

What is the formula to calculate kinetic energy?

If a car has a mass of 1000 kg and is moving at a speed of 20 m/s, what is its kinetic energy?

• 200,000 J

• 20,000 J

• 2,000 J

• 200 J

Which of the following factors does NOT affect an object's kinetic energy?

• Mass

• Speed

• Color

• Both A and B

If the speed of an object doubles, what happens to its kinetic energy?

• It doubles

• It quadruples

• It halves

• It remains the same

What unit is kinetic energy measured in?

• Newtons

• Joules

• Kilograms

• Meters per second

If two objects have the same speed, but one has twice the mass of the other, how does the kinetic energy of the heavier object compare to the lighter one?

• It is the same

• It is twice as much

• It is four times as much

• It is half as much

What happens to the kinetic energy of an object if its speed is halved?

• It is halved

• It is quartered

• It remains the same

• It doubles

A ball with a mass of 2 kg is rolling at a speed of 3 m/s. What is its kinetic energy?

• 9 J

• 18 J

• 6 J

• 3 J

If the kinetic energy of an object is 50 J and its mass is 10 kg, what is its speed?

• 1 m/s

• 2.24 m/s

• 5 m/s

• 10 m/s

Why does kinetic energy increase with the square of speed?

• Because energy is directly proportional to mass

• Because energy is directly proportional to the square of speed

• Because energy is inversely proportional to speed

• Because energy is inversely proportional to the square of speed
