The overall force of gravity becomes stronger and stronger. This is because the gravity depends on the inverse of the square of the distance:
and since the distance r between the molecules becomes smaller, the gravity increases more and more.
Answer
given,
mass of ice hockey player = 110 Kg
initial speed of the skate = 3 m/s
final speed of the skate = 0 m/s
distance of the center of mass, m = 30 cm = 0.3 m
a) Change in kinetic energy
b) Average force must he exerted on the railing
using work energy theorem
W = Δ KE
F .d = -495
F x 0.3 = -495
F = -1650 N
the average force exerted on the railing is equal to 1650 N.
They all study under some sect of science.
And they all study under different sects of science ie. Biologist study of life Geologists study of Geology, and Physicists study of physics.
