newton's 3 laws of motion (1st law) |
1ST LAW: AN OBJECT AT REST WILL STAY AT REST, AND AN OBJECT IN MOTION WILL STAY IN MOTION UNLESS ACTED UPON BY AN UNBALANCED FORCE.
Newton's first law of motion affects every volleyball player who botches a serve and sends the ball snacking into the net. Every player who blocks a hard-hit ball from an opposing player feels the law's effect on her stinging arms. The server's hand, the net, and the blocker's forearms acted as an unbalanced force that stopped, or changed, the direction of the ball, the object in motion. |
There are other scientific components that are present in volleyball such as work and velocity.
Work is defined as the displacement of an object due to force. The corresponding equation being work = force x distance. Therefore, when one of the players comes in contact with the volleyball, the work would be how much force is exerted from the player and how far the ball travels as a result. Passing is one of the most basic concepts yet involves many aspects of science. Velocity is the speed of the movement, and it is calculated by using the equation velocity = displacement/time. A person would calculate this to determine the velocity at which the volleyball travels after being served or spiked. A higher velocity means that the volleyball is traveling faster and as a result more difficult to return. |
