24-25 Energy Study Guide

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It is the energy an object has when it is at rest and has the potential to move.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and the speed at which it is moving.

Front

How does potential energy change when an object is lifted?

Back

When an object is lifted, its potential energy increases because it is moving against the force of gravity.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases and is converted into kinetic energy.

Front

What is the relationship between potential energy and mass?

Back

Potential energy is directly proportional to the mass of the object; the greater the mass, the greater the potential energy.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of the particles in an object.

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting potential energy to kinetic energy.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

How does temperature affect the kinetic energy of particles?

Back

As temperature increases, the kinetic energy of particles increases, causing them to move faster.

Front

What is an example of energy conversion in a battery-powered device?

Back

In a battery-powered device, chemical energy from the batteries is converted into electrical energy, which is then transformed into thermal energy and light energy.
