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

What is the formula for calculating kinetic energy?

Back

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

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses because of its height above the ground. It is calculated as PE = mass (m) * gravity (g) * height (h).

Front

What factors affect gravitational potential energy?

Back

Gravitational potential energy is affected by the object's mass, the height above the ground, and the acceleration due to gravity.

Front

What is chemical potential energy?

Back

Chemical potential energy is the energy stored in the bonds of chemical compounds, like food, batteries, and gasoline.

Front

How can potential energy be converted to kinetic energy?

Back

Potential energy can be converted to kinetic energy when an object is allowed to move, such as when a ball is dropped.

Front

What happens to kinetic energy when an object slows down?

Back

When an object slows down, its kinetic energy decreases.

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

How does height affect potential energy?

Back

The higher an object is lifted, the more gravitational potential energy it has due to its increased height.
