Week 16 - Potential and Kinetic Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It has the potential to be converted into kinetic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and the speed at which it is moving.

Front

How does height affect potential energy?

Back

The higher an object is positioned, the more potential energy it has due to the gravitational force acting on it.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 * mass (m) * velocity (v)^2.

Front

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

Back

As a roller coaster climbs, potential energy increases and kinetic energy decreases. As it descends, potential energy decreases and kinetic energy increases.

Front

What are examples of chemical potential energy?

Back

Examples include food, batteries, gasoline, and wood.

Front

What happens to energy during a roller coaster ride?

Back

Energy transforms between potential and kinetic energy as the coaster moves up and down hills.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy held by an object because of its 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

What is the principle of conservation of energy?

Back

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