Solution:
W = F × s = 20 N × 3 m = 60 J
Efficiency = (Work done / Energy input) × 100% = (4900 J / 5000 J) × 100% = 98% Solution: W = F × s = 20
First, calculate the work done:
where F is the force applied and s is the displacement of the object. Solution: W = F × s = 20
Energy is the ability to do work. There are two main types of energy: kinetic energy and potential energy.
Efficiency = (Work done / Energy input) × 100% Solution: W = F × s = 20
Solution:
