What is Work?

Back

Work is defined as the product of the force applied to an object and the distance over which that force is applied. It is calculated using the formula: Work (W) = Force (F) × Distance (d). The unit of work is Joules (J).

What is the formula for calculating Work?

Back

The formula for calculating work is W = F × d, where W is work, F is force in Newtons, and d is distance in meters.

What is Energy?

Back

Energy is the capacity to do work. It exists in various forms, including kinetic energy, potential energy, thermal energy, and more.

Front

What is Kinetic Energy?

Back

Kinetic energy is the energy of an object due to its motion. It is calculated using the formula: KE = 0.5 × m × v², where m is mass in kilograms and v is velocity in meters per second.

What is Potential Energy?

Back

Potential energy is the energy stored in an object due to its position or configuration. For gravitational potential energy, it is calculated using the formula: PE = m × g × h, where m is mass, g is acceleration due to gravity, and h is height.

What is the formula for Potential Energy?

Back

The formula for gravitational potential energy is PE = m × g × h.

Front

What is Power?

Back

Power is the rate at which work is done or energy is transferred. It is calculated using the formula: Power (P) = Work (W) / Time (t). The unit of power is Watts (W).

Front

What is the formula for Power?

Back

The formula for power is P = W / t, where P is power in Watts, W is work in Joules, and t is time in seconds.
