Give an example of an object with high potential energy.

• A ball at the bottom of a valley

• A roller coaster at the top of a hill

• A car parked on a flat road

• A feather falling from a tree

Explain the concept of gravitational potential energy.

• The energy released when an object falls to the ground

• The energy stored in an object due to its speed

• The energy stored in an object due to its position in a gravitational field.

• The energy produced by the rotation of the Earth

How is potential energy related to the position of an object?

• Potential energy is not related to the position of an object

• Potential energy is only related to the speed of an object

• Potential energy depends on the position of an object.

• Potential energy is constant regardless of the position of an object

What is kinetic energy?

• Energy from the sun

• Energy an object possesses due to its motion

• Energy from food

• Energy stored in an object

Define mechanical energy.

• The energy of sound waves

• The sum of potential energy and kinetic energy in an object

• The energy produced by machines

• The energy stored in food

Explain the relationship between potential and kinetic energy in the context of mechanical energy.

• Potential energy and kinetic energy are completely unrelated

• Potential energy can be converted into kinetic energy and vice versa

• Potential energy is always greater than kinetic energy

• Kinetic energy can only be converted into potential energy

• Thermal energy and sound energy

• Chemical energy and electrical energy

• Nuclear energy and solar energy

The Law of Conservation of Energy states:

• Energy can created or destroyed but not transformed 
• Energy cannot be created or destroyed, it can only transformed
• Energy can't be created, destroyed or transformed
