What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, often associated with height in a gravitational field.

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in units like kilometers per hour (km/hr) or meters per second (m/s).

What is the formula to calculate speed?

Back

The formula to calculate speed is S = d/t, where S is speed, d is distance, and t is time.

What does it mean when we say energy cannot be created or destroyed?

Back

It means that energy can only be transformed from one form to another, but the total amount of energy remains constant.

What type of energy is stored when a spring is compressed?

Back

Elastic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, dependent on its mass and velocity.

What is the formula for kinetic energy?

Back

The formula for kinetic energy is KE = 1/2 mv^2, where KE is kinetic energy, m is mass, and v is velocity.

What is the relationship between potential energy and kinetic energy on a roller coaster?

Back

As a roller coaster descends from a height, potential energy is converted into kinetic energy, increasing the speed of the coaster.
