Our bodies emit heat, and nerve endings in our skin can detect it.
Our eyes can detect visible light, but our bodies don't emit that.
Explanation:
Terminal velocity is given by:
Here, m is the mass of the falling object, g is the gravitational acceleration, is the drag coefficient, is the fluid density through which the object is falling, and A is the projected area of the object. in this case the projected area is given by:
Recall that drag coefficient for a horizontal skydiver is equal to 1 and air density is .
Without drag contribution the motion of the person is an uniformly accelerated motion, thus:
the puck recoils in each case.
larger mass stone gives puck greater recoil, smaller stone, smaller recoil
The rocket engine works on the basic principle proposed by Newton which is Newton’s Third Law.
