Science Coursework Investigation:

Ball Rebound 

Ball Rebound

Apparatus:

  •  Golf Ball
  • Metre Ruler
  • Thermometer

Golf Ball: This piece of apparatus is the key part of my investigation. We will be testing how high the golf ball will rebound up when it is dropped from different heights. This piece of apparatus is crucial.

Metre Ruler: This piece of apparatus will help us unfalteringly have a precise result when measuring the height of what the golf ball reached when dropped. It will also help show us precisely where to drop the golf ball as we increase in height.

Thermometer: This piece of apparatus will be used to record the temperature of the room when the experiment is taking place. This is to see if the temperature of the room has any effect on the end result of the experiment.

The factor that I am going to vary in this investigation to make it as different and as accurate as possible is the release height. The release height will vary as we increase the height of where we will drop the golf ball. This means we can see the variety of how far apart each result is for example the fact of how much speed the ball will get by being dropped from a higher height. This factor is important.

The Factor I intend to measure to provide my results is the rebound height of the golf ball. This is a key factor in my investigation; this will show me the different results of how high the rebound height is of the golf ball, when dropped at different heights. The variety of different heights will show me how different the rebound height is. The rebound height will be measured by the metre ruler, someone will be standing on a chair next to the ruler which will be stuck to the wall. The ball will be dropped at different heights and caught at the highest peak of its rebound.

The factors I will keep the same throughout the whole investigation are:

  •  Golf ball
  • Room Temperature
  • Floor

Golf Ball: This factor will have to stay the same to keep the investigation just and fair. The same golf ball should be used to measure every rebound height. If I change the golf ball then it could cause the investigation to be unfair as the golf ball may vary in its shape, size etc.

Room Temperature: This factor is something that I cannot change. The room temperature will stay the same throughout the whole investigation, ...
