Then, calculate the efficiency:

A 10 kg object is lifted to a height of 4 m above the ground. Calculate its gravitational potential energy. Then, calculate the efficiency: A 10 kg object

A 50 N force is applied to a block, causing it to move 2 m to the right. Calculate the work done on the block. Then, calculate the efficiency: A 10 kg object

W = F × s = 50 N × 2 m = 100 J

Solution:
