Centripetal force: The centripetal force is the force that pulls or pushes an object towards the center of its circular path, allowing it to stay on the circular track.
Velocity:Velocity refers to how fast an object moves in a specific direction. In this case, it determines how quickly and in what direction the cart moves along the circular track.
Friction:Friction is a force between two surfaces that resists their relative motion. In this case, friction between the wheels of the cart and the surface of the track helps keep it from sliding off.
