A ball is dropped from rest and falls towards the ground. Air resistance is negligible. Which graph shows the variation with speed of the height of the ball above the ground?
- AGraph A: height above ground decreasing linearly with speed from a positive value to zero
- BGraph B: height above ground increasing linearly with speed from zero
- CGraph C: height above ground decreasing with speed, curve concave downward
- DGraph D: height above ground increasing with speed, curve concave upward
