Circular motion is the movement of an object along a circular path, where the object's distance from a fixed point remains constant while its direction continuously changes.
Centripetal force is the force that acts on an object moving in a circular path, directing it towards the center of the circle. It is responsible for keeping the object moving along the circular path.
The centripetal force can be calculated using the formula: F = (mv^2)/r, where F is the force, m is the mass of the object, v is the velocity, and r is the radius of the circular path.
Tangential acceleration is the rate of change of an object's tangential velocity, while radial acceleration is the rate of change of an object's radial velocity. Tangential acceleration is directed along the tangent to the circular path, while radial acceleration is directed towards the center of the circle.
The speed of an object in circular motion is directly proportional to the radius of the circle. This means that as the radius increases, the speed of the object also increases. This is because a larger radius requires a faster speed to cover the same distance in the same amount of time.
