Potential and Kinetic Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion, calculated using the formula KE = ½(mass) x (velocity)².

Front

What is the formula for calculating Kinetic Energy?

Back

KE = ½(mass) x (velocity)².

Front

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state, commonly gravitational potential energy.

Front

What is the formula for Gravitational Potential Energy (GPE)?

Back

GPE = (mass) x (acceleration of gravity) x (height).

Front

What unit is used to measure energy?

Back

The unit for energy is Joule (J).

Front

How does mass affect Kinetic Energy?

Back

Kinetic Energy is directly proportional to mass; 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 velocity; if velocity doubles, Kinetic Energy increases by a factor of four.

Front

At which position does a child on a swing have maximum Kinetic Energy?

Back

At the lowest point of the swing's arc.

Front

At which position does a child on a swing have maximum Gravitational Potential Energy?

Back

At the highest point of the swing's arc.

Front

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

Back

In a closed system, the total mechanical energy (Potential Energy + Kinetic Energy) remains constant.
