Quarterly B: Potential and Kinetic Energy

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 the height of an object above the ground.

Front

How is Kinetic Energy calculated?

Back

Kinetic energy (KE) can be calculated using the formula: KE = 1/2 mv², where m is the mass of the object and v is its velocity.

Front

How is Potential Energy calculated?

Back

Potential energy (PE) can be calculated using the formula: PE = mgh, where m is the mass, g is the acceleration due to gravity, and h is the height above the ground.

Front

What happens to Potential Energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, illustrating the conversion between the two forms of energy.

Front

What is the relationship between Potential and Kinetic Energy?

Back

Potential energy can be converted into kinetic energy and vice versa. For example, when an object is lifted, it gains potential energy, and when it falls, that energy converts to kinetic energy.

Front

What is an example of Kinetic Energy in everyday life?

Back

An example of kinetic energy is a moving car. The faster the car moves, the more kinetic energy it has.

Front

What is an example of Potential Energy in everyday life?

Back

An example of potential energy is a book placed on a shelf. It has potential energy due to its height above the ground.

Front

What is the highest point of a thrown ball called in terms of energy?

Back

At the highest point of a thrown ball, the energy is mostly potential energy.

Front

What is an example of the conversion of Potential Energy to Kinetic Energy?

Back

A roller coaster descending from the top of a hill is an example of potential energy converting to kinetic energy.
