Mechanical Energy

Front

What is mechanical energy?

Back

Mechanical energy is a form of energy that is the sum of potential energy and kinetic energy in an object due to its motion and position.

Front

What are the two main types of mechanical energy?

Back

The two main types of mechanical energy are kinetic energy (energy of motion) and potential energy (stored energy due to position).

Front

How do animals use mechanical energy?

Back

Animals use mechanical energy to perform work, such as flying, swimming, or running.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

Can you give an example of kinetic energy?

Back

An example of kinetic energy is a person walking.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

How do humans use mechanical energy in sports?

Back

Humans use mechanical energy in sports to perform actions like kicking a ball, throwing, or jumping.

Front

What factors affect kinetic energy?

Back

Kinetic energy is affected by the mass of the object and the speed at which it is moving.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the relationship between potential energy and height?

Back

Potential energy increases with height; the higher an object is positioned, the more potential energy it has.
