Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It is the energy that 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 square of its velocity.

Front

How is kinetic energy calculated?

Back

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

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, assuming no energy is lost to air resistance.

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy is directly proportional to the mass of the object. If the mass doubles, the kinetic energy also doubles, assuming the velocity remains constant.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object possesses due to its height above the ground, calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

At which point does a pendulum have maximum potential energy?

Back

A pendulum has maximum potential energy at the highest points of its swing.

Front

At which point does a pendulum have maximum kinetic energy?

Back

A pendulum has maximum kinetic energy at the lowest point of its swing.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is an example of energy transformation?

Back

An example of energy transformation is a person walking up a hill, where kinetic energy is converted into gravitational potential energy.
