Because the gravity pulls use towards the ground and our bones can’t take the amount of weight hitting the surface
Because they know physics :)
higher amplitude => higher potential energy => more to transform into kinetic energy => higher speed => higher range (distance)
The answer for this question is negative externality
Well, according to Newton’s second law of motion, the formula he had devised would be
Fnet = m • a
N = kg • m/s^2
In terms of mass and acceleration, it would be that 1 N = 1 (kg•m/s^2).
