Energy Flashcard

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and the speed at which it is moving.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It is often associated with gravitational energy when an object is elevated.

Front

Where is kinetic energy the least when a baseball is tossed?

Back

At the highest point of its trajectory, where its speed is momentarily zero.

Front

What happens to the kinetic energy of an object if its mass increases?

Back

The kinetic energy increases, as kinetic energy is directly proportional to mass.

Front

What type of energy is NOT produced by a fire?

Back

Electrical energy is not produced by a fire; fires primarily produce light, thermal, and sound energy.

Front

What happens to particles in a substance as it heats up?

Back

As a substance heats up, its particles gain energy and move faster.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the relationship between mass and potential energy?

Back

Potential energy increases with an increase in mass, as it is calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is thermal energy?

Back

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

Front

What is the principle of conservation of energy?

Back

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