Forces lab

Abstract: The previous lab explored the effect of gravity on free fall. It was determined that acceleration is always constant under free fall. However, in this lab, acceleration was observed under different forces, other than Just gravity. Therefore, depending on how strong the forces being exerted were, acceleration differed. It wasn’t constant anymore. Using a glider on a air track and a pulley, different masses were attached at the end of the string and the glider was allowed to move on the air track and the movement of the glider were analyzed using Auditions.

Percent error for when m=egg is 7. 24% and for m=egg, percent error is 30. 43%. 4. Sources of error: Although, the air track was friction-less, the pulley that was bearing the weight, wasn’t Traction-Tree. I en Traction Trot ten pulley tattletale played a role In ten obtained G values Maybe the air track wasn’t fully friction-free due to technical difficulties, which accounts for the obtained data with 30. 43% error (even with multiple trials).

Maybe the string wasn’t leveled out before performing each trial, which created more friction in some trials than the others. 5. When m was made twice as large, acceleration was increased by a factor of 1. 41 . Since ma, and if m and a both increased, the Fine also increased. If m was left unchanged, and M was twice as large, the data would still be the same because M as on air track and it was frictionless, so the mass of M would not affect the data. 6.

Although from Lab 1, it was concluded that acceleration due to gravity is independent of mass, this lab involved a non-gravitational force acting on the acceleration as well as gravitational force, and since F=ma, mass is also a factor effecting acceleration in this lab. 7. If the string between m and M was cut, then M would still run back and forth on the air track because there wouldn’t be any friction stopping it from running and m would free fall in the ground because gravitational Orca would be the only force acting on it if the string was cut 8.

There should be no friction present between M and the surface of the air track to keep the system stationary. Friction would exert a force on M and therefore would prevent the system from being stationary. Conclusion: Acceleration is always constant under free fall, however, when other forces are being introduced to the situation, acceleration will react to it and not be constant anymore. If mass goes up, acceleration also goes up, and since F=ma, F will be also be higher.
