Kinetic and Potential Energy

In the figure, kinetic energy is being converted into potential energy from which point?

• point A to point B

• point B to C

• The only energy involved here is kinetic energy

• Energy is not being converted

What kind of energy is the energy in motion?

When you are holding a book, energy is stored between the book and Earth. Which type of energy occurs on it?

A moving 50 kg object has 30 Joules of KE. What is its velocity?

• 1.0 m/s

• 1.1 m/s

• 1.2 m/s

• 1.3 m/s

What will happen to the kinetic energy if the mass is doubled?

• Nothing will happen

• Remains the same

• Doubled

Answer explanation

The kinetic energy of the object is directly proportional to the mass, therefore on doubling the mass kinetic energy will also become double.

When you stretched a rubber band, you are storing which kind of energy?

Calculate the potential energy of a 8 kg box with a height of 2.52 m.

At which point is potential energy GREATEST?

In order to INCREASE the gravitational potential energy of an object, which do you need to?

• Put the object lower to the ground

• Raise the object higher

Which is the best example that something has kinetic energy?

• a car parked on a steep hill

• a tennis ball rolling across the court

• a picture hanging on the wall

• a piece of coal before it's burned
