Bennet Clark Analysis

In this video olympic swimming athlete Bennet Clark demonstrates a race start with the help of his Cal swim team coach and the laws of physics! Clark’s dive can be related back to Newtons 1st law of motion. This law states that “An object at rest stays at rest and an object in motion stays in motion with the same speed and direction, unless acted upon by an unbalanced force” In this video the athlete is at rest when he is first on the starting block. He is being acted upon by normal force between him and the block. When he bends down to pull with all his strength on the block he is creating a tension force between him and the block. He then gets power and pushes off the block with both feet. He is accelerating into the air and being acted upon by an unbalanced force. He is changing his motion and is no longer in constant motion. …show more content…
This law is when a force is being put on an object but it isn't balanced nor equal. When Bennett pushes off the block he is no longer at rest therefore unbalanced forces are acting upon him. Bennett is the object and his mass compared to the block’s mass causes his acceleration to happen when he pushes off the block and into the air. There is also a friction force when he is positioning his feet on the block to move his feet kinetic friction is in action.

In newtons 3rd law “ for every action their is an unequal and opposite reaction” Their isn't an action when Bennet is at rest with his two feet still on the block. However when he pushes off he is making an action occur that is resulting in a reaction, which then causes him to accelerate. However he accelerates at a constant speed still and aa constant. The force of gravity is what causes him to enter the water after being in the
