A satellite goes round the earth in a circular orbit with constant speed is the motion uniformly accelerated
Answers
It has constant speed, but not constant velocity. Since it is moving in a circular orbit, the body changes its direction of motion at every single instant (at a tangent). This implies that velocity is not constant.
Uniform circular motion, but the satellite is accelerated towards the centre of the earth.
» According to Newton's Second Law, the satellite is accelerating because it experiences a net force acting on it, and also because its velocity is changing.
» The direction of the satellite's acceleration is not tangential to the circular motion, but rather perpendicular to its velocity/towards the centre of the earth.
» This acceleration is a result of earth's gravitational force on the satellite. The acceleration is also known as centripetal acceleration.
