Explanation:
In order for a hypothesis to be tested, and experiment needs to be designed.
Many trials need to be runned in order to get accurate results and to form a valid conclusion that can prove or disprove the hypothesis
The impact of the material
type with which the slope is made affects the acceleration. Acceleration will
be higher and smoother if the material of the slope surface is smoother as
opposed to a texture which is not smooth. Smoother surface allows more acceleration
because it will have less friction and resistance. Otherwise the friction will
slow the object down for example a grassy ground will have more friction than a
well maintained marble floor.
