9702Gravitational potential energy and kinetic energy
An object is released from rest at time t = 0 and falls downwards through a long distance. Air resistance is negligible. Which graph shows the variation of the kinetic energy E_K of the object with time t?
- AGraph A: E_K against t, straight line through origin with positive gradient
- BGraph B: E_K against t, curve through origin with decreasing gradient
- CGraph C: E_K against t, curve through origin with increasing gradient
- DGraph D: E_K against t, straight line with negative gradient starting from positive E_K
