The athletic event of hammer throw is a metal ball attached to a wire and handle. However, there are certain forces acting on both the athlete and the ball when participating in this event. The force of upward force and gravity takes part when the athlete grabs the handle from the ball; the force of acceleration takes part when the ball is pinning; when the ball is throw out, Newton's First Law results both on the athlete and the ball; finally, the force of air resistance and gravity takes part when the ball is thrown out and land, Newton's First and Third Law could easily be observed on the ball too. Hammer throw relies on these actions of forces. However, all of these contribute to the sport of hammer.
             The hammer is a metal ball attached to a wire and a handle. Athletes throw it with a spinning motion similar to that used in the discus event. The athlete grips the handle with both hands and while keeping the feet stationary whirls the ball around in a circle above the head. The hammer gains momentum as the athlete spins the body around three times; at the point of greatest speed, the athlete releases the hammer upward and outward.
             First of all, when the athlete grab the ball handle with her/his hand and trying to lift it to be able to spin it, the force of upward force and gravity takes part in this procedure. Because he/she has to lift the ball, he/she has to use a force to pull the ball up from the ground; this is called the upward force. But there is also another force pulling the ball down, which is gravity that makes it difficult for the lift of the ball. However, in this case, if the athlete grab the ball successfully up from the ground, then there will be an unbalanced force, in which the upward lift force is greater than the gravity, which pulls it down.
             Secondly, the force of acceleration takes part when the ball is spinning. When the ball was successfully grabbed up from the ground, the athlete then has t
