Potential vs. Kinetic Energy

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. For example, a rock at the top of a hill has potential energy because of its height.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has. For example, a rolling ball has kinetic energy.

Front

How is Potential Energy calculated?

Back

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

Front

How is Kinetic Energy calculated?

Back

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

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

Give an example of energy transformation from Potential to Kinetic Energy.

Back

When a roller coaster descends from the top of a hill, its potential energy is converted into kinetic energy as it speeds up.

Front

What factors affect Potential Energy?

Back

Potential Energy is affected by the mass of the object, the height above the ground, and the strength of the gravitational field.

Front

What factors affect Kinetic Energy?

Back

Kinetic Energy is affected by the mass of the object and its velocity. Increasing either will increase the kinetic energy.

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the potential energy an object has due to its height above the ground, influenced by gravity.

Front

What is Mechanical Energy?

Back

Mechanical Energy is the sum of potential energy and kinetic energy in an object. It represents the total energy of motion and position.
