How much power does it take to lift a 5 kg
WebJan 29, 2016 · The force required to lift an object is its weight (the force of gravity) Weight: F g = mg. I will use 10 for g, you may be using 9.8 or 9.81 in your class. F g = 30kg ⋅ 10 N kg = 300N. W = F d. W = 300N ⋅ 3 2 m. W = 450J. Answer link. WebJan 30, 2024 · On earth it takes about 10 Newton-meters (N-m) of energy to raise a 1 kilogram mass to a height of 1 meter. Since 1 N-m equals 1 Joule, that’s 10 Joules. If it takes 1 second to lift the weight 1 meter, than you have converted 10 Joules of energy to potential energy in one second. That’s 10 Watts of power.

WebFeb 27, 2024 · For an apple with mass m = 0.1 kg hanging at a height h = 2.5 m, the gravitational potential energy is E = 2.4525 J, or roughly half a calorie. To find this result, multiply m by h and by g, with g = 9.81 m\s²: E = 0.1 kg · 2.5 m · 0.81 m/s² = 2.4525 J. Is potential energy the same as kinetic energy? Not exactly. WebMay 25, 2024 · If the object is higher than the ground level, it gains potential energy. We can calculate the potential energy of objects above ground level using the equation given …

(Unit = W) WebNov 8, 2015 · Lifting the weight at a certain speed requires power from end to end, always measured in watts. At the output, the power to lift the weight is speed*force in m/s and N. …
WebSay you have a 1kg mass at end of string and you raise the mass 1m at a constant speed. Then you lower the mass 1m. The amount of work to raise it is F*d = ma*1m = mg*1m = 1kg (9.8m/s/s) (1m) = 9.8J But to lower it it is the exact same calculation but it doesnt make intuitive sense to me. Webor putting it another way, if you lift the mass at a velocity v the power is: (2) W = m g v (because v = h/t). So to take your example of a 10kg weight, to lift this at a speed of 1 m/s would require a power: W = 10 × 9.81 × 1 = 98.1 W which is …
Webthe power produced is: 80 foot-pounds/1 minute = 80 foot-pounds per minute.
