What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. It is often associated with gravitational potential energy, calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

How do you calculate Kinetic Energy?

Back

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

How do you calculate Potential Energy?

Back

Potential Energy (PE) is calculated using the formula PE = mgh, where m is the mass of the object, g is the acceleration due to gravity (approximately 9.81 m/s²), and h is the height above the ground.

Front

What happens to Kinetic Energy when speed increases?

Back

As the speed of an object increases, its Kinetic Energy increases exponentially because it is proportional to the square of the velocity.

Front

What happens to Potential Energy when height increases?

Back

As the height of an object increases, its Potential Energy increases linearly, as it is directly proportional to height.

What is the relationship between Kinetic and Potential Energy in a pendulum?

Back

In a pendulum, Kinetic Energy and Potential Energy are inversely related; as one increases, the other decreases, maintaining a constant total energy.

Front

At which point in a pendulum's swing is Kinetic Energy greatest?

Back

Kinetic Energy is greatest at the lowest point of the swing, where the speed is highest.

Front

At which point in a pendulum's swing is Potential Energy greatest?

Back

Potential Energy is greatest at the highest points of the swing, where the height is maximum.

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.
