This is a Race Track Interactive Activity. I need help to aswer this question please. I uploaded easy track and medium track.    Did you need to keep applying a force to keep the car turning on the track? What direction did you have to apply that force? Be specific and don’t just say “left or right.”

A satellite is moving at constant speed in a circular orbit about the Earth, as represented in the diagram below. Orbit 7シ Earth R T Satellite The net force acting on the satellite is directed toward which of the following points? A Q B R C D T の

Centripetal Force: I'm trying to understand the forces at work in centripital force, i understand that if an object is moving in a circle then their must be a net inward acceleration. So if centripetal force is what is pushing in on the object toward the center of the circle, then what is pushing outward to counteract this force and hold the object in its rotation? Like a tenis ball on a string, if i swing it and it gain an inward force, then as it swings under that logic it would approach my hand. What is pushing it out?
