S1S4 Energy & Force Review

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 speed at which it is moving.

Front

How is Potential Energy calculated?

Back

Potential Energy (PE) can be calculated using the formula: PE = mgh, where m is mass, g is the acceleration due to gravity, and h is the height above the ground.

Front

How is Kinetic Energy calculated?

Back

Kinetic Energy (KE) can be calculated using the formula: KE = 1/2 mv², where m is 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 Mechanical Energy?

Back

Mechanical Energy is the sum of potential energy and kinetic energy in an object that is used to do work.

Front

What is Energy Transfer?

Back

Energy Transfer is the process of energy moving from one object or system to another, often changing forms in the process.

Front

What is an example of Mechanical to Thermal Energy transfer?

Back

An example of Mechanical to Thermal Energy transfer is when friction between moving parts generates heat.

Front

What is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the relationship between Potential Energy and height?

Back

The higher an object is positioned, the greater its potential energy due to the increased gravitational force acting on it.
