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
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).
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.
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.
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.
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.
two watts a second
Power = (energy) / (time) = (35 x 5) / 19 = 175 newton-meters / 19 seconds = 9.2105 watts (rounded)
Yes, if the velocity of the object is increased.
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).
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.
Power = (energy) / (time) =(200 newtons x 4 meters) / (4 seconds) =200 newton-meters per second = 200 watts
his force is clearly 200N
