Work, Power, and Energy (Physical Science)

Front

What is Work in physics?

Back

Work is done when a force causes an object to move in the direction of the force. It is calculated as Work = Force x Distance.

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 Energy?

Back

Energy is the ability to do work. It exists in various forms, including kinetic energy, potential energy, thermal energy, etc.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It is calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or configuration. For example, a raised object has gravitational potential energy.

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.

Front

What is a Fossil Fuel?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, used as energy sources. Examples include coal, oil, and natural gas.

Front

What is the formula for calculating Work?

Back

Work = Force x Distance x cos(θ), where θ is the angle between the force and the direction of motion.

Front

What is the unit of Work?

Back

The unit of Work is the Joule (J), which is equivalent to one Newton meter (N·m).

Front

What is the unit of Power?

Back

The unit of Power is the Watt (W), which is equivalent to one Joule per second (J/s).
