Acceleration Lab We Believe That By Using A Ramp And A Marble

**Aspect 1**

The aim of this experiment is to prove that acceleration due to gravity is 9.81 m/s.

**Hypothesis**

We believe that by using a ramp and a marble that we will be able to prove that acceleration due to gravity is 9.81 m/s.

**Explanation**

We think this will happen because gravity pulls the marble down to the bottom of the ramp, and if acceleration due to gravity is 9.81 m/s then the data from the trials will show that it is true.

**Predictive Graph**

If I were to make a graph for this experiment it would be a velocity and time graph with a straight line that goes in a positive direction; as the time increases the velocity does too.

**Variables**

Independent Variable: Starting point for marble

Dependent Variable: How long it takes the marble to get to the end of the ramp

Controlled Variable: acceleration due to gravity
