What directions are T and Fg in? How do you add and subtract forces that act in different directions?claytonwideman said:Fc = T-Fg
Circular motion refers to the movement of an object along a circular path around a fixed point or axis. This type of motion requires a centripetal (inward) force to keep the object in its circular path.
Centripetal force is the force that acts towards the center of a circular path, keeping an object in its circular motion. It is necessary for an object to undergo circular motion as it balances out the object's inertia, preventing it from moving in a straight line.
Centripetal force can be calculated using the equation Fc = (mv^2)/r, where Fc is the centripetal force, m is the mass of the object, v is the velocity, and r is the radius of the circular path.
Centripetal force and centripetal acceleration are directly proportional to each other. This means that as the centripetal force increases, so does the centripetal acceleration, and vice versa.
No, an object cannot move in circular motion without a centripetal force. Without this force, an object will continue moving in a straight line due to its inertia.
