Potential, Kinetic, and Energy Transformaitons

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 a substance.

Front

What factors affect potential energy?

Back

Potential energy depends on mass and position relative to a reference point, such as height above the ground.

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

Where is kinetic energy maximum on a roller coaster?

Back

Kinetic energy is maximum at the bottom of a big hill on a roller coaster.

Front

What is the transformation of energy when a rubber band is released?

Back

The transformation is from elastic potential energy to mechanical energy.

Front

What is the definition of 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 the energy transformation in glow sticks?

Back

The light produced by glow sticks is a conversion from chemical energy to radiant energy.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses because of its position in a gravitational field, often calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

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

Back

In a pendulum, kinetic energy is highest at the lowest point of the swing, while potential energy is highest at the highest points of the swing.

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.
