QUESTION 1: How do we see Newton's 1st and 2nd Laws while passing a basketball?
Starting off, Newton's First Law states that an object in motion will stay in motion and an object at rest will stay at rest, unless acted upon by an outside force. Newton's 2nd Law states that for a particular force, the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object. The direction of the force is the same as that of the acceleration. To complete a pass, there are many factors and forces that influence to ball. To begin a pass, a player must exert a force on the ball, and the ball leaves the players hand, it becomes a projectile. A projectile is affected by two components. When we look at the X- Component, we see Newton's First Law in Action.. Newton's 1st Law in the X component is and object in motion traveling in a straight line will stay in motion on a straight line as constant velocity unless acted upon by an outisde force. This is becuase there are no forces in the X compoenent. As we look at the Y component, we are able to see Newton's 2nd Law in action. as the ball is accelerated by 9 .8 m/s^2. Because of this, the ball will take a downward path, so in order to have a successful pass, you would need to through the ball higher that your target. Another thing that affects the pass is whether you target is moving or not. If still, all you would need to do it pass the pass slightly higher. Although, is the player is moving, you would need to lead him in order to complete the pass.. After the ball leaves the players hands, it will continue in the direction the hands forced it in. Therefore, you would need to pass the ball in front of a moving target, or else the ball would be behind you target.
QUESTION 2: How come placing spin on the ball causes a more likely chance for it to go in the basket when it hits the rim or back board?
When a basketball with spin hits a backboard or rim, it causes the direction of the spin to change in the opposite direction, and decrease its velocity. Also, spin causes more friction when it hits a rim or backboard, which causes a drastic decrease in velocity. Without spin, the ball would just bound right off the backboard at the same angle it came in at. The force of gravity also helps the ball drop into the hoop after hitting off the backboard.
The Physics of Basketball !!
This is the FBD of the forces acting on the ball after it has left the players hands. The force of gravity is the only force acting on the ball at this point.
