## Relative position of a helicopter

If a helicopter takes off from a point on earth.(at certain altitude) and its still at that point in air.After certain time interval the observer whose position was same as that of helicopter’s take off point will see the helicopter right above him. The question arises is that how it is possible if [...]

## Relative velocity in free fall

If a person jumps out of a plane, and a few seconds later, another person jumps, why is it that the difference in their velocities stays the same? Shouldn’t it decrease because eventually, the first diver will reach maximum velocity, but the other diver will be slower at first, but then he reaches max. velocity [...]

## Relative motion in 3D (three dimension)

I wanted to ask that is there relative velocity in three dimennsion? if yes then explain it. (Apoorv Katoch asks) Answer: As we know, motion is relative. Relative velocity can be defined in three dimension also. Relative velocity is defined as the velocity of one body when the other is assumed to be at rest. [...]
