Lab Report: Impulse and Momentum Essay

In the world of science this is a one-dimensional model and keeps the mathematics simpler. In this experiment, obtained values were. When the plunger is activated, the carts push away from each other and are propelled in opposite directions. This source of error could lead to a miscalculation of the final momentum as well as the percentage error. In the fourth scenario cart one collides inelasticlly with cart two, which is two times the mass of cart one with cart two originally at rest. If two materials remain constant then the coefficient of restitution will be a constant. Download file to see next pages Read More.

Conservation of Momentum Lab by Lauren Pinion on Prezi

Egg Drop activities are loads of phun. Add 1 mass block to each magnetic cart. Measure the speeds of each of the marbles after the collision. Collision 3 - Inelastic with No Added Mass 14. These collisions will be run for three pairs of marbles, each pair will be similar in mass. The moment of inertia was also calculated a second way, using the radii and masses of the disk and ring.

However, since this experiment is made in a laboratory where the temperature is always constant at room temperature, the only factor that affects the coefficient of restitution between two bodies in the collision is the types of the two materials are made of. How well do your results support the theory of conservation of momentum? To analyze this data, we want to check to see if conservation of momentum holds. Journal of Analytical Toxicology, 28 6 , pp. Position-time data are used to determine the pre- and post-collision speeds of the cart and the brick. Pick a cart, put it on a track and slam it into a second cart. Consider two side-by-side carts on a low-friction track.

Through this lab, we furthered our knowledge on the conservation of momentum theory. Wind-generated electricity is also viable since it is already in use, in many countries. This activity involves the analysis of a collision between a moving cart and a dropped brick that lands on top of it. Another source of error which could arise is the dynamics track could be off balance. Collision 2 - Elastic with Added Mass 9. However, to conclude with even more accurate data, a completely horizontal surface parallel to sea level will conclude with more precise data.

This collision will be repeated for marbles of three different sizes. Lab Summarized During the first part of the lab, the moments of inertia for a spinning disk with and without a weighted ring on top were calculated using two different methods. Vary the masses and repeat step 3 pushing carts 2. This is because there is no external forces act on the system. We are going to choose the positive direction to be from Motion sensor 1 to Motion sensor 2.

Manually push both carts to create the collision. Mass of disk M : 1. Just how smart is a marble? Videos of the collision and the seconds just before and after were taken. In scenario three cart one elastically collides with cart two, which is now three times the mass of cart one. When a collision occurs in a closed system that has no force other than the force of momentum, momentum before and after the collision is equal. In addition, there was also taking of distance measurements separating photogate eyes for each trial because it they were subject to change after each propelling trial of the ball. The puck and air table are unfamiliar to students - this raises the probability that the students will, in their own minds, see the whole thing as magic.

Conservation of Momentum

The individual momentum values of the two objects are calculated before and after the collision and analyzed. Find the average of these two values and record as v f in Table 1. Our hypothesis was supported because our line of best fit had a slope of 0. Spinning objects tend to continue to spin. Would need a greaseless lubricant. An object with more mass has more momentum, and an object with more velocity also has more momentum. Lastly, if the string ever caught a snag while unraveling, this would have also contributed to the error.

Having velocity simply means that an object has a speed and direction. But, this is unlikely to happen in real case because there is always some energy loss, whether through deformation, heat or sound. The coefficient of restitution is the ratio of speeds of a falling object, from when it hits a given surface to when it leaves the surface. The accompanying activity sheet is intended for use with a classroom; its emphasis is on the use of science reasoning skills to understand the physics behind an egg drop activity. In laymen's terms, the coefficient of restitution is a measure of bounciness.

If the disk was dropped at and angle and did not make complete contact with the disk at the same instant, this could have also caused error. The limitations of the experimental setup were that it is difficult to drop the ring on the spinning disk perfectly. Possible sources of error include our lack of trials and the assumption that both carts originally had a mass of 250 grams. It basically is a property of collisions and depends upon the materials that are colliding. By taking the equation 1 for an integration, it shows that the impulse due to a force over a given time period is equal to the change in momentum as shown in equation 2. It can be said that the impulse acting on an object is equal to the change in momentum of the object.

Record the interval as d in Table 1. Conservation of momentum says that momentum is neither created nor destroyed; it only moves from one place to another. In this experiment external forces such as applied force and friction are used on the carts. Raw data Data table 1 showing raw data collected during experiment. One cannot just add all the momentums and hope for the best: the units are different.
