Centripetal Force – The force required to keep an object moving in a circular path, directed towards the center of the circle.
Tension in a String – The force exerted by a string or rope when it is pulled tight by forces acting from opposite ends.
Newton's Second Law – The relationship between the force acting on an object, its mass, and its acceleration (F = ma).
