What is gravitational force?

Hey!!!!

Here's your answer:

The mutual force of attraction between any two objects of this universe due to their masses is called gravitational force.

Look at the attached picture...

Detailed information is given about gravitation in the attached picture

Hope it will help you...

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
