Question

because the acceleration of an object moving in a circle is always in the direction of the net force acting on it, there must be a net force toward the of the circle. this or center - seeking force is exemplified by the suns force on earth to keep earth in its orbit, or by the tension in the chain of a hammer swung by an athlete. need help? review these concept resources. read about the concept

Explanation:

When an object moves in a circle, according to Newton's second law (\(F = ma\)), since the acceleration (\(a\)) of a circular - moving object (centripetal acceleration \(a=\frac{v^{2}}{r}\) where \(v\) is the tangential velocity and \(r\) is the radius of the circle) is towards the center of the circle, the net force (\(F\)) must also be towards the center. The term for a center - seeking force is centripetal force. The Sun's gravitational force on the Earth provides the centripetal force for the Earth's orbital motion.

Answer:

center, centripetal, gravitational
