Cart Lab
Hypothesis-
The more weight exerted on the string the faster the cart will accelerate.
Procedure-
· Place tracks on table
· Attach string to cart and put cart on tracks
· Set up pulleys so that string extends over the end of the table and hangs down
· On the end of the string hanging over the table, place 20 grams of mass on string and 2490 grams on the cart.
· Place motion detector on track to read motion of cart.
· Allow cart to slide down track. Sliding will be caused by the gravitational pull exerted on the hanging mass.
· The motion detector will then record the speed of the cart.
· Record the Data and repeat with different masses while still keeping the same total mass on the system.

Conclusion-
My hypothesis was proven correct. The more weight on the hanging end of the string, the greater the net force, making the cart move faster. The lighter the hanging mass, the slower the cart moved. The acceleration, no matter the weight of the hanging mass, cannot exceed 9.8 meters per second per second because the force acting upon it is gravity. The force that makes the hanging mass not go 9.8 meters per
