Kinetic&Potential Energy

Front

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.

Front

What is Potential Energy?

Back

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

Front

How does mass affect Kinetic Energy?

Back

The greater the mass of an object, the more kinetic energy it has at a given velocity. Kinetic energy is directly proportional to mass.

Front

How does velocity affect Kinetic Energy?

Back

Kinetic energy increases with the square of the velocity. This means that if the velocity doubles, the kinetic energy increases by a factor of four.

Front

What happens to Kinetic Energy when an object slows down?

Back

As an object's velocity decreases, its kinetic energy also decreases.

Front

What is the relationship between Kinetic Energy and stopping distance?

Back

The greater the kinetic energy of an object, the longer the stopping distance required to bring it to a stop.

Front

At what point does a pendulum have maximum Kinetic Energy?

Back

A pendulum has maximum kinetic energy at the lowest point of its swing, where its speed is greatest.

Front

At what point does a pendulum have maximum Potential Energy?

Back

A pendulum has maximum potential energy at the highest points of its swing, where its speed is zero.

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

How does height affect Potential Energy?

Back

Potential energy increases with height. The higher an object is positioned, the more potential energy it has due to the gravitational force acting on it.
