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

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

The electric current For ball mill alicey023 The working efficiency directly affects the concentrator economic benefits of the beneficiation factories. Therefore improve the efficiency of the mill is very important. Generally speaking‚ the factors restricting the improvement of the efficiency as following: 1. The electric current For ball mill‚ enlarging the current is to increase the rotate speed. If the has high rotate speed‚ its work efficiency will be high. However‚ there is one notice:

Bouncing Balls Coursework P3 1. Work out the average bounce height and put results in a table. Draw graph of the drop height against bounces height label axis. 2. Looking at my data‚ it is evident that when the drop height is 200cm for instance the average bounce height is 67cm compared to a shorter drop height of 120cm which has a average bounce height of only 50cm. This shows that when the drop height is higher the bounce height is also higher. 3. My data is good as I ensured that it was

The Ball Python is an important organism in many ecosystems. The snake helps out a lot in all ecosystems around them by different ways they live. The food web of the snakes and other organisms in an ecosystem helps to show how the snakes live in their habitats and help make a community. Snakes are simple animals. These non-venomous constrictors use their forked tongue to detect different odors from their prey. The Ball Python strikes with great velocity and kills by constriction. The snake’s diet
