Statement:
If you push a large, heavy ball up a ramp (inclined plane), you push will less force.
Solution:
- Let us consider the force applied on the ball be F. Let the displacement be s.
- We know the formula of work,
- W = F s, where W is the work done.
- or, F = W/s
- or, F ∝ W and F ∝ 1/s
- So, force applied is directly proportional to the work done and inversely proportional to the displacement.
- We know, energy is the capacity of a body to do work.
- So, in other words, the amount of energy = work done.
- We have already got that force is directly proportional to work done.
- So, force is also directly proportional to the amount of energy.
- And we have got force is inversely proportional to distance.
- So if force is less, then work and energy will be less. However, the distance will be more.
- Hence, it will be option c.
Answer:
c. The distance you push it.
