lab

This lab is a very good lab for high school physics.

It makes students think of what needs to be measured in order to find the velocity of a marble sliding across a table and falling off. This is great for the Projectile Motion unit. Also it gives students an understanding of how to keep variables constant (in this case the speed of the marble is kept constant because of the ramp set at a constant angle at a constant distance from the edge of the table).

This lab is great for analysis of motion graphs (d vs. t, v vs. t, a vs. t) and how to change them one into another in a detailed manner. At the end, the students should find the acceleration due to gravity from the slope of the best fit line of the graph of v vs. t.

This lab, can give really great results (within 5% error) if the students do the right calculations.
