Which point has maximum potential energy?

If two springs S1 and S2 of force constants k1 and k2, respectively, are stretched by the same force, it is found that more work is done on spring S1 than on spring S2.

Statement 1 : If stretched by the same amount, work is done on S1, will be more than that on S2

Statement 2 : k1 < k2

A particle is acted upon by a force F= kx, (k > 0) where x is the displacement of particle. If potential energy at origin is zero then the potential energy of the particle varies with x as

A particle moves under the influence of a force given by F = cx, where c is a constant and x is the distance covered. The energy gained by the particle moving from x = 0 to x = 4 is :

An object of mass 10 kg falls from rest through a vertical distance of 10 m and acquires a velocity of 10 m/s. The work done by the push of air on the object is (g = 10 m/s²)

As the object gains speed, it's G.P.E (Gravitational Potential Energy

If energy loss is zero then the decrease in G.P.E is equal to
