The density of the golf ball in the lab is higher than the average density of a golf ball. This means that the golf ball was made for long shots in the golf course. The neutral buoyancy was successfully achieved when the molarity of the solution was 3.33M. Therefore‚ if the water hazards in golf ball courses had a higher molarity than 3.33M‚ then golf balls would float to the surface. However‚ repeated errors in the lab might have caused inaccurate calculations. For example‚ the beaker was too small

factor that affects the height of a bouncing ball. The factor that will be investigated in this experiment would be the initial height of the ball. The relationship will be determined by altering the initial height of the ball prior to the release in order for the ball to bounce. The ball used in this experiment would be a tennis ball‚ and it will be dropped on the same surface each experiment. However‚ the initial height prior to the release of the ball will be altered in order to determine the true

the Golf Ball One factor that greatly affects the flight and trajectory of a golf ball is the air resistance. People may think that air resistance would make the golf ball slower and drop faster‚ but this is not true. Modern golf balls have adapted to this by having circular shallow depressions‚ also known as “dimples‚” on the ball. This was invented by a English engineer William Taylor in 1908. Unlike other designs‚ the dimple proved to be the most aerodynamically efficient. Dimpled balls fly farther
