Why does one get hurt jumping from a great height to the floor?
The quantity of motion of a moving body is measured as a product of its mass and velocity. According to Newton's second law of motion, the force applied is directly proportional to the rate of change in momentum.
Mathematically, momentum can be represented as:
p is the momentum.
m is the mass.
v is the velocity.
The reason why one gets hurt jumping from a great height to the floor:
Therefore, one injures oneself when one jumps from a higher vantage point.
