Admin How high does a basketball bounce when dropped from 5 feet?
According to international basketball rules, a basketball is properly inflated “such that when it is dropped onto the playing surface from a height of about 1.80 m measured from the bottom of the ball, it will rebound to a height, measured to the top of the ball, of not less than about 1.2 m nor more than about 1.4 m” …
Does drop height affect bounce height?
If the drop height increases, then the resulting bounce height will also increase, because as the drop height increases, so does the gravitational potential energy which can be converted back into kinetic energy on the rebound.
How high does an average basketball bounce?
For example, depending on the type of basketball and surface, you may have seen the ball bounce about 15 inches high on carpet and about 25 inches high on concrete.
How do you calculate how high a ball bounces?
Between the first and second bounces, the height can be expressed as h = 140 − 16(t − 6.49)2, 3.54 ≤ t < 9.45. The 6.49 is when the highest point is achieved (halfway between the two bounces), and the 9.45 seconds is derived from adding 3.54 seconds to the time between the first and second bounces.
How high should a NBA basketball bounce when dropped?
Rule 1-12-2 says: “The ball shall be inflated to an air pressure such that when it is dropped to the playing surface from a height of 6 feet, measured to the bottom of the ball, it shall rebound to a height, measured to the top of the ball, of not less that 49” when it strikes on its least resilient spot, nor more than …
Do basketballs lose their bounce?
Yes, the age of a basketball will affect how well the ball bounces. An old basketball may have very slowly leaked some of its air out and become flatter than a new one. An important difference between basketballs and tennis balls however is that you can reinflate a basketball to give it its bounce back.
How did the GPE change with height?
Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.
Why do balls bounce higher when dropped from a greater height?
Because the ball is softer than the floor, it does most of the denting and stores most of the energy. When you drop a ball from a greater height, it has more kinetic energy just before it hits the floor and stores more energy during the bounce—it dents farther as it comes to a stop.
