Conservation of Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a child at the top of a slide has potential energy because of its height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. For example, a snail crawling across a leaf has kinetic energy.

Front

What does the law of conservation of energy state?

Back

The law of conservation of energy states that energy can be converted from one form to another, but it cannot be created or destroyed.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of kinetic energy and potential energy in a system.

Front

Give an example of an object with kinetic energy.

Back

A roller coaster car just before it goes downhill.

Front

What happens to potential energy when an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is an example of energy conversion?

Back

An oven converting electrical energy to thermal energy.

Front

What is the relationship between kinetic and potential energy in a closed system?

Back

In a closed system, when kinetic energy increases, potential energy decreases, and vice versa.

Front

What is an example of potential energy?

Back

A parked car in the driveway has potential energy due to its position.

Front

What does it mean for energy to be transferred?

Back

Energy transfer refers to the movement of energy from one object or system to another.
