Question

A particle moves in circular path with decreasing speed. What happens to its angular momentum?
The kinetic energy associated with a satellite is E. What is the total energy associated?​

Answer 1

Explanation:

A particle moves along a circular path with speed, then the angular momentum is given by

L

=

r

×

p

=

r

×m

v

When the speed v decrease, the magnitude of of angular momentum decreases. But the direction of angular momentum remains constant.
