Newtons second law Rishi Changela

Average speed Trial 1 0.37628866 Trial 2 0.37532134 Trial 3 0.45341615

Acceleration Trial 1 = meter per second ÷ seconds = 0.55 ÷1.28=0.42 meter per second per second Trial 2 =0.73 ÷ 1.32 = 0.55 meters per second per second Trial 3 = 0.73÷0.97=0.75 meters per second per second

Force Trial 1 kg times acceleration = 0.05 divided by 1.28 =0.039n Trial 2 0.57 divided by 1.32=0.43n Trial 3 0.15 divided by 0.75=0.2 n AIM Of the experiment is to test newtons second law and explore the relationship of mass and acceleration and whether an n object moves with a fast acceleration when the size of the pulling force is increased and to see the impact of mass on acceleration of an object

Hypothesis If we increases the mass it will increases the impact with acceleration

Materials Physics cart

1m thread 80cm wooden ramp Stop watch 1m ruler 50 , 100 , 150 grams weights

Variables The independent variable is that the weight [mass] of the weight is altered because of the diffent mass added The controlled variables the distance the cart was rolling down on was the same for all of the three trials The dependent variable is that the time and the speed changed because of the different masses added

Safety Take care when the masses fall to the floor because they can hurt when they fall to the ground and also p revent toes or fingers from being in the drop zone

Discussion For the results to be valid you need the people who working in the group like Chloe , Lhin , Simon , Hillary and my self-needed to work together so that our results can be the same. The person needs to stop the car on time so that it does not pass 0.73 cm can it does not fall of the bench and the person has to stop the timer on time. Some of the statistics were hard to convert so some of the data might is wrong or the time might have been stopped a bit late. The changes we need is that we need to focus on the weight when it hits the ground and stop the timer.
