    Questions about the formula for acceleration

    Homework Statement I know that acceleration = change in velocity/change in time. Wouldn’t acceleration therefore also = distance/time2? I thought this was true until i learned the formula for motion s=ut*1/2at2 where s = distance and u = initial velocity Here, if you re-arrange the...

    How Does Measuring Voltage Before and After an Experiment Impact Uncertainty?

    How does taking the voltage of a circuit before and after an experiment help with uncertainty in the voltmeter? Our teacher instructed us to do this, and i got that voltage before was 1.516 and voltage after was 1.498. Does this mean the voltmeter became less resistant? How do I turn this...

    Acceleration vs Force graphWhat am I doing wrong?

    Well for each trial we used a motion sensor and software program that took the velocity and time and graphed it. Then we chose an area from the graph and took ΔV/Δt to get the acceleration.

    Acceleration vs Force graphWhat am I doing wrong?

    hmm weird. I put it in word instead

    Acceleration vs Force graphWhat am I doing wrong?

    I considered that myself, but I checked with my lab partner and we had the same values for weights and everything. It’s hard to believe that could be it. @Bandersnatch I attached my raw data

    Acceleration vs Force graphWhat am I doing wrong?

    I’m not really sure If we’re thinking the same My instruction for this experiment was to “use the raw data to confirm Newton’s second law” which I assumed (according to F=ma) would be to see if the acceleration of the cart is proportional to gravitational force. The total mass of the trolley...

    Acceleration vs Force graphWhat am I doing wrong?

    I have to confirm Newtons 2nd law via a track and trolley experiment Homework Statement The trolley’s mass is kept constant. The weight of the cart (252g) plus two bar weights (500g) is = 752 grams, plus additional weights of either, 10g, 15g, 20g, 25g or 30g for the different trials...

    Finding the Mass from an Acceleration vs Force graph

    We used a motion sensor which took the velocity/time for each trial. the Average acceleration I posted there is the average of 5 trials for each of the different acceleration masses.
