How fast can you spin a basketball?

The average rotation rate of the made foul shots was 6.76 radians per second. This is about a one and one tenth full rotation of the basketball every second. Image two demonstrates the range of the made baskets’ rotation rates is 1.41 radians per second.

Why do NBA players spin the ball?

The end result of this is to put a bit of backspin on the ball, which not only makes for gorgeous slow-motion images in sports replays or basketball movies but also gives the shot a better chance of bouncing in. The effect of spin comes from the other piece of the motion.

Why does a ball slow down in water?

By the First Law of Motion, if there are no forces acting on an object, an object conserves the same speed. The water’s drag force slows down the billiard ball, just like anything moving underwater.

Can a beach ball float in water?

Gravity pulls down more than buoyancy pushes up, so the rock sinks to the bottom. A beach ball, on the other hand, is much lighter than a beach-ball-sized blob of water, so in this case buoyancy beats gravity. It floats! In general, if an object is less dense than water, it floats.

How does density affect floating and sinking in water?

Key Concepts. Density is a measure of how heavy something is compared to its size. If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float.

What causes buoyant force?

The buoyancy force is caused by the pressure exerted by the fluid in which an object is immersed. The buoyancy force always points upwards because the pressure of a fluid increases with depth.

Which finger spins the easiest ball?

Find an old basketball. Using an old ball for spinning is actually better for beginners. The grooves in an older ball are worn down, making it easier for your finger to stay on target and balance while you spin the ball.
