A rocket has been fired upwards to launch a satellite in its orbit. Name the two forces acting on the rocket immediately after leaving the launching pad (Ignore the frictional force due to air resistance).
We saw in Newton's laws of motion that if we apply an external unbalanced force on a ball,it will move and also will come to a stop because of gravitational pull and also frictional force. If we do the same thing in space,will the ball come to a stop?
Because,in space there is no frictional force and no gravitational pull,so will it come to stop?
When light travels from rarer to denser medium,speed decreases, and when it comes out from denser medium speed increases...we know that if a body changes its speed or acceleration.. force needs to be applied...so which force makes it to speed up or slow down..while going through denser to rarer...which force acts on it to increase the speed???
