Physics - Work, Power, and Energy

Front

What is Work in Physics?

Back

Work is defined as the product of force and the distance over which it acts. It is calculated using the formula: Work = Force x Distance.

Front

What is the formula to calculate Work?

Back

Work = Force x Distance

Front

What is the SI unit of Work?

Back

The SI unit of Work is the Joule (J).

Front

What is Power in Physics?

Back

Power is the rate at which work is done or energy is transferred. It is calculated as Power = Work / Time.

Front

What is the SI unit of Power?

Back

The SI unit of Power is the Watt (W).

Front

What does the symbol 'F' represent in the work formula?

Back

In the work formula, 'F' represents Force.

Front

What is Energy in Physics?

Back

Energy is the capacity to do work. It exists in various forms, such as kinetic energy, potential energy, thermal energy, etc.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object due to its motion, 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 of an object due to its position or state, commonly calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is the relationship between Work and Energy?

Back

Work done on an object results in a change in its energy. If work is done on an object, its energy increases.
