Max force on the no airbag is significantly higher and, in some trials, more than double the force. Finally, when we compare the airbag trials with the no airbag trials, we can see that the Hypothesis we made was correct because the airbag was the best at handling forces in theĬollision. Should be no force applied on the cart for it to have negative velocity. The final two test are inelastic collisions because there Will not compress as much which means that the duration of the collision will be shorter, andįorce will not be absorbed as much.

Max force and initial velocity is higher in the stronger spring. When we compare the weak spring to the strong spring we can see that the ratio of the There should be a similarity to the impulse measured and the impulse calcuated with theįormula. This made sense because the weak spring can increase the duration of the collision due to itsĪbility to compress more before pushing the cart back. We noticed that the weak spring had the lowest max force. The first two tests are elastic collisions because The data table shows the results ofĪll four tests and the number of trials for each (In order: Weak Spring, Strong Spring, Airbag, No There are two types of collisions, elastic and inelastic. Vi (m/s) Vf (m/s) ∆p (kg m/s) F∆t (Ns) % diff Max Force (N) To see how accurate the change in momentum from the calculated and the measured, theĮrror percentage formula can acquire that. In an inelastic collision, the object will have a final velocity of zero due to the object In an elastic collision, the two objects bounce off of each other, which means there is aĬhange in momentum and the initial and final velocity are essentially the same in magnitude. Integral, or by finding the area under the curve. The impulse can be calculated by taking the Light one), an air bag, and nothing, or a wall. To test the different types of collisions, there will be two different springs (a heavy and The values will be tested by calculations andįormulas. Then be testes to see how accurate they are. The impact will be measured and recorded into a graph. The initial and final velocity, as well as the force of Of a force over time is equal to momentum. Instead of evaluating force of motion with F=ma, momentum can be used. Objective(s): Gain a better understanding of elastic and inelastic collisions and the relationshipīetween the integral of force overtime and impulse.
