Work, Power, and Simple Machines remediation

Work is done when a force causes an object to move. It is calculated as the product of force and distance (Work = Force x Distance).

The unit of work is the Joule (J). 1 Joule is equal to 1 Newton meter.

Work done is calculated using the formula: Work = Force x Distance.

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

The unit of power is the Watt (W). 1 Watt is equal to 1 Joule per second.

A simple machine is a device that makes work easier by allowing us to apply force in a more efficient way. Examples include levers, pulleys, and inclined planes.

A pulley is a simple machine that consists of a rope or chain wrapped around a wheel, used to lift or move loads.

30 Joules (Work = Force x Distance = 10 N x 3 m).

50000 Joules (Work = Force x Distance = 5000 N x 10 m).

190 Watts (Power = Work / Time = 950 J / 5 s).
