Uniform circular motion is the motion of an object moving in a circular path at a constant speed. This means that the object is traveling in a circular path with the same speed and direction at all times.
The velocity of an object in uniform circular motion can be calculated by dividing the distance traveled around the circle by the time it takes to make one complete revolution. This is also known as the circumference divided by the period.
Angular velocity refers to the rate at which an object rotates around a central point, while tangential velocity refers to the speed of the object in a circular path. Angular velocity is measured in radians per second, while tangential velocity is measured in meters per second.
The centripetal force is the force that keeps an object moving in a circular path. It acts towards the center of the circle and is responsible for changing the direction of the object's velocity, but not its speed. Without this force, the object would move in a straight line instead of a circular path.
Yes, an object in uniform circular motion can have a changing speed if the radius of the circle it is traveling in changes. This would result in a change in the magnitude of the centripetal force, which would cause a change in the speed of the object.
