Somebody make an experiment for me that will prove newton's 2nd law. I need to be able to conduct this experiment tomorrow so make it realistic.

Best idea gets 50K luts  hocuspocus;

i can't do your homework for you sorry awdood;

idk you could make a pulley. gather different weights of different masses. put one on each side of the pulley. measure how fast they fall/rise. also put two identical weights to show that there is no acceleration at all when the forces cancel.

enjoy your 0

Nah I have some ideas i just figure that Boyah will have some better ones.

Here's what I'd do:

First, let's assume that acceleration for a dropped object is constant for the experiment. Ge a 100 g weight, and a spring with a platform on it. The spring will have spring constant k, according to Hooke's law, and you can experimentally test this value. The platform you will have to weigh, and it'll already depress the spring a bit, and you need to factor that in. When you drop the spring on, if the acceleration is proportional to the force (as Newton's 2nd predicts), the spring should depress a certain amount each time. If the thing is striking with a constant force, then it should depress the same amount no matter what height it is dropped from.

At least, I think. It's been a while since physics. Maybe if you do the data, it's linear, and if you divide each value by the distance you dropped it from (based on the thing having a certain potential energy, and a unit of N x m). But maybe not. I forget. That's all I got.

If you want to vary the experiment with different accelerations, you can roll the weight down a slope and have it hit the thing.
