Question

How can I makeup a physics scenario that includes concepts of work and energy. Should I make something going up or down a ramp!? JUST a SCENARIO plss!!!I'm stressed! I need to be able to make a solution for this made up scenario that includes work and energy calculations.

Answer 1

Work done = 100 Nm

Potential energy = 250J

Step-by-step explanation:

A person carrying a heavy weight of load without moving does no work. But the load will surely experience potential energy.

Work will be done when he or she covers a little distance.

If the weight of the load = 25 N and the distance covered is 4 metres, the workdone will be the product of the weight and distance covered. That is,

WD = F × d

WD = 25 × 4 = 100Nm

Let assume that the height of the man is 10 m tall.

The load will be experiencing potential energy of mgh. That is,

P.E = mgh

Since weight W = mg

Substitute weight and height into the formula

P.E = 25 × 10 = 250J
