Acceleration takes place the first 0-30 meters or to about 3-4 seconds from the start of a sprint. After approximately 30 meters acceleration turns into maximum velocity and top speed is hit.
In science, a hypothesis is an idea or explanation that you then test through study and experimentation. Outside science, a theory or guess can also be called a hypothesis. A hypothesis is something more than a wild guess but less than a well-established theory. In science, a hypothesis needs to go through a lot of testing before it gets labeled a theory. In the non-scientific world, the word is used a lot more loosely.
A hypothesis is an educated guess. For example A basketball will bounce higher on asphalt than on grass.. The hypothesis must also be testable, meaning the student must have access to the equipment and terrain to carry out the experiment.Another science fair project, studies how hand placement affects basketball shooting.
