Kinetic and Potential Energy

Front

What is the definition of kinetic energy?

Back

Kinetic energy is the energy that an object possesses due to its motion, calculated as ½(mass) x (velocity)².

Front

What is the definition of potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, often associated with height in a gravitational field.

Front

How does mass affect kinetic energy?

Back

Kinetic energy is directly proportional to the mass of the object; as mass increases, kinetic energy increases if velocity remains constant.

Front

How does velocity affect kinetic energy?

Back

Kinetic energy is proportional to the square of the velocity; if velocity doubles, kinetic energy increases by a factor of four.

Front

At what point in a pendulum's swing is kinetic energy the highest?

Back

Kinetic energy is highest at the lowest point of the pendulum's swing.

Front

At what point in a pendulum's swing is potential energy the highest?

Back

Potential energy is highest at the highest points of the pendulum's swing.

Front

What is the formula for calculating potential energy?

Back

Potential energy is calculated using the formula: PE = mass x gravity x height.

Front

What happens to kinetic energy as an object slows down?

Back

As an object slows down, its kinetic energy decreases.

Front

What is the relationship between kinetic and potential energy in a closed system?

Back

In a closed system, the total mechanical energy (kinetic + potential) remains constant, demonstrating the principle of conservation of energy.

Front

What is an example of potential energy in everyday life?

Back

An example of potential energy is a book on a shelf, which has gravitational potential energy due to its height.
