Energy Transformation Quiz

What is meant by kinetic energy?

• Energy stored in an object

• Energy produced from motion

• Energy derived from the sun

• Energy produced from heat

Potential energy is the energy possessed by an object due to:

• Its motion

• Its position or state

• The temperature of the object

• The shape of the object

The most common example of renewable energy is:

• Crude oil

• Natural gas

• Solar energy

• Coal

How is electrical energy generated from potential energy?

• By converting heat energy into electrical energy

• By using water turbines

• By utilizing motion energy

• By converting light energy into electrical energy

If an object falls from a height, its potential energy will:

• Increase

• Decrease

• Remain the same

• Change into electrical energy

Heat energy can be used for:

• Moving cars

• Cooking food

• Generating electricity

• All of the above

If we have two types of energy, namely kinetic energy and potential energy, how can we calculate the total mechanical energy?

• Mechanical energy = Kinetic energy + Heat energy

• Mechanical energy = Potential energy - Kinetic energy

• Mechanical energy = Kinetic energy + Potential energy

• Mechanical energy = Potential energy x Kinetic energy

What happens to energy when a car suddenly stops?

• Kinetic energy changes to potential energy

• Kinetic energy changes to heat energy

• Potential energy changes to kinetic energy

• Energy does not change

Why is renewable energy better than fossil energy?

• Renewable energy cannot be used

• Renewable energy is cheaper

• Renewable energy does not produce pollution

• Renewable energy is harder to obtain

How can we create electrical energy from motion energy?

• By using solar panels

• By using wind turbines

• By using batteries

• By using heaters
