Power (the rate of energy use) is calculated as the product of the energy exerted (work) divided by the time over which the energy is released.

P = W/t

To solve the example, multiply the force in Newtons by the displacement in meters to find the work in joules, then divide by the time to find the power required, in watts (joules/second, or kg-m2/sec3)

100 N x 10m = 1000 joules divided by 10 seconds = 100 watts

An object is lifted 2 m in 5 seconds by a force of 100 N.?

The work done to lift the object is 200 J (Work = Force x Distance). The power exerted to lift the object is 40 watts (Power = Work / Time).


What is the power of a machine that lifts a N object 4 in 6 seconds?

The power of the machine can be calculated using the formula Power = Work/Time. Given that Work = Force x Distance, and the force required to lift the object will be its weight (N), the power can be calculated using the force (weight of object) and the distance it is lifted in the given time frame.


How much power would a person use to move a piano 10 meters in 5 seconds using a force of 100 newtons?

Power is equal to work done divided by time, where work done is force multiplied by distance. In this case, the work done is 100 newtons * 10 meters = 1000 joules. Therefore, the power used would be 1000 joules / 5 seconds = 200 watts.


A child kicks a stone along the sidewalk with a force of 520 newtons. The stone travels 1.5 meters in 0.30 seconds. How powerful is the child's kick?

The power of the child's kick can be calculated using the formula: Power = Work / Time. Work is calculated as Force × Distance, which in this case is 520 newtons × 1.5 meters. Time is 0.30 seconds. Therefore, the power of the child's kick is 260 watts.


How much power would it take to move a chair 5 meters in 15 seconds using a force of 51 newtons?

The power required to move the chair can be calculated using the formula Power = force x distance ÷ time. Plugging in the values: P = 51 N x 5 m ÷ 15 s = 17 Watts. Therefore, it would take approximately 17 Watts of power to move the chair 5 meters in 15 seconds using a force of 51 Newtons.
