Energy transfers and transformations

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. The faster an object moves, the more kinetic energy it has.

Front

What happens to kinetic energy when an object comes to a stop?

Back

When an object comes to a stop, its kinetic energy is transformed into other forms of energy, such as heat and sound.

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 particles in an object.

Front

How is thermal energy transferred?

Back

Thermal energy is transferred through conduction, convection, and radiation.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a ball held at a height has gravitational potential energy.

Front

What is the process of photosynthesis?

Back

Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen, transforming radiant energy into chemical energy.

Front

What is radiant energy?

Back

Radiant energy is energy that travels in waves and can move through empty space, such as light from the sun.

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

What is an example of energy transformation?

Back

An example of energy transformation is when a light bulb converts electrical energy into light and thermal energy.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating sound waves, which can be heard when they reach a person's or animal's ear.
