Day 93: Finding the Mass of My Car Using Newton’s Laws
This is a classic physics activity. A student pushed my car (in neutral) with a constant force so the car would accelerate due to his push. We measure his pushing force with a bathroom scale, time and distance with stopwatches and a trundle wheel. We did this on a slight incline to compensate for friction.
Pushing force = 50 lbs = 222 N
distance = 10 m
time = 11 s
What’s the mass of my car?
