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.

An athlete initiates uniform circular motion when throwing a hammer or a discus by imparting angular momentum to the object. This is typically achieved by rotating their body while holding the hammer or discus. As the athlete rotates, they generate angular velocity, causing the object to move in a circular path around them. By transferring energy through the rotation of their body, the athlete imparts the necessary momentum to the object, allowing it to follow a curved trajectory when released. This circular motion enables the athlete to generate greater velocity and distance when throwing the hammer or discus in a sports event.
