Forms of Energy and Transformations

Front

A lamp begins with electrical energy when plugged in and turns into _________ energy when the light comes on.

Back

Radiant energy is the energy of electromagnetic waves, which is what we see as light.

Front

Gravitational potential energy depends on the ________ and ________ of the object.

Back

Gravitational potential energy depends on the height and mass of the object.

Front

When work is done, there is always a(n) _______.

Back

There is always a transfer of energy when work is done.

Front

What is work?

Back

Work is the product of force and displacement, causes a change in potential energy of an object, and does not depend on the path traveled, but only on the starting and ending position.

Front

Energy is stored in the ___ of an atom.

Back

Energy is stored in the nucleus of an atom.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object based on its position or state, such as gravitational potential 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

What is mechanical energy?

Back

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

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to temperature.
