Hello all. I performed an experiment in Physics class to attempt to answer the following question:
How will changing the mass of a trolley affect its acceleration when it goes down the slope?
I changed the mass of a trolley on each trial, let it go down a slope, and measured its acceleration. I added a total of 50 grams to the trolley but the acceleration always remained constant. I am perplexed as to how this happened.
- Dependent (measured): acceleration
- Independent (being changed): mass of trolley
- Controlled (kept stable): angle of slope and distance traveled
F = ma
The Attempt at a Solution
Newton's Second Law states that mass and acceleration are inversely related (i.e, if mass increases, acceleration should increase), but such case did not happen. How did it not?
