Answer:
Newton's first law of motion describes the motion of satellites in an orbit around the earth.
Step-by-step explanation:
According to "Newton's first law of motion", if a body is at rest, it will stay in rest until or unless an external or an unbalanced force is applied to the body to make it move. A satellite has a forward thrust, which is offset by the gravity of the earth and keeps the satellite orbiting around its orbit not falling into the earth. The momentum that the satellite gained from its launch combined with the gravity of the earth causes the satellite to go into orbit above the earth.
