KE and GPE Calculations

Front

What is Kinetic Energy (KE)?

Back

Kinetic Energy is the energy an object possesses due to its motion. It is calculated using the formula KE = 1/2 mv^2, where m is mass and v is velocity.

Front

What is Gravitational Potential Energy (GPE)?

Back

Gravitational Potential Energy is the energy an object has due to its position in a gravitational field. It is calculated using the formula GPE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What factors affect Gravitational Potential Energy?

Back

Gravitational Potential Energy is affected by the mass of the object and its height above the ground.

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.8 m/s².

Front

What is the correct unit for measuring energy?

Back

The correct unit for measuring energy is Joules (J).

Front

What is the formula for calculating Kinetic Energy?

Back

The formula for calculating Kinetic Energy is KE = 1/2 mv².

Front

What happens to Kinetic Energy as an object's speed increases?

Back

As an object's speed increases, its Kinetic Energy increases, since KE is proportional to the square of the velocity.

Front

What is the relationship between Kinetic Energy and mass?

Back

Kinetic Energy is directly proportional to the mass of the object; if mass increases, Kinetic Energy increases, assuming velocity remains constant.

Front

What is the total mechanical energy of an object?

Back

The total mechanical energy of an object is the sum of its Kinetic Energy and Gravitational Potential Energy.

Front

How does height affect Gravitational Potential Energy?

Back

As the height of an object increases, its Gravitational Potential Energy increases, since GPE is directly proportional to height.
