First we will get to know what are the basic forces acting on a satellite while orbiting around Earth.
“We let the Gravity work for us.” Using natural existing gravitional force for our necessity and advancement.

Atmospheric drag
Solar radiation pressure
Gravitional perturbations due to other space bodies and
J2 perturbations due to oblateness of Earth.
There is a constant tug-of- war between momentum of satellite(to move in a straight line) and gravity force (attracts towards Earth) resulting Satellites to move around in circular or elliptical orbits.
Now, lets see how the satellite gets that momentum part. We humans had created big cannons called Rockets, which propel the satellites to higher orbits (our necessity to establish large coverage networks and for Earth observation and reseasch advancement), injecting satellites at 7 km/s to 10 km/s based on desired orbits. That momentum or impulse given to the satellite tends to move in a straight path which is also induced by gravity forces let the satellite to travel in an orbit.
Image: We need to give sufficient energy to the satellite to orbit, or else it will fall off to the ground itself. With rockets we achieve that orbit injection velocity requirements.
