Question

Look at the picture below. The boy is swinging back and forth on the swing. At which point is the potential energy of a swing the greatest?

Point A (top)


Point B (halfway down)


Point C (bottom)


Point D (halfway up)

Answer 1

the correct answer is Point A the top

Answer 2

Point A (top)

Potential energy is the energy possessed by an object due to its height relative to a reference level. so greater the height above the reference level, greater will be the potential energy.

when the boy is at the top, the height is maximum there. hence the potential energy of the boy is maximum at the Top.
