Similar to the stone example, once the hammer or discus is released, it continues moving in the direction it was moving at the time of release due to its inertia. The object maintains its velocity and direction unless acted upon ...

The athlete initiates uniform circular motion by rotating their own body while holding the hammer or discus, giving it a circular motion. This circular motion imparts angular momentum to the object.

Uniform speed in uniform circular motion means that the object covers equal arc lengths in equal intervals of time. This ensures that the object moves around the circle at a constant rate, maintaining a consistent angular velocity.

In uniform circular motion, the direction of motion of the object changes continuously as it moves along the circular path. At each point on the circle, the object’s velocity vector is tangent to the circle, indicating the direction of its ...

When a stone is released from uniform circular motion, it continues to move along a straight line tangent to the circular path because it retains the direction of motion it had at that instant. This is due to the principle ...
