However, there is certain point where its velocity will be constant. When an object starts falling down, its velocity increases. We can draw some conclusions from our graph and data related to drag force and velocity. In this lab, we study the relationship between air drag forces and the velocity of a falling object. To improve the lab, we could maybe use something like aВ DopplerВ Radar or something to precisely measure the time it takes for one revolution and would therefore decrease human error by a substantial amount. Possible sources of error in this lab were when I was spinning the mass on the string, I didn't always spin it with a constant velocity, the person timing the fifty revolutions might not have stopped the stopwatch exactly when the mass made its fiftieth revolution, and the string and spring have mass as well, but we do not really compare to the weight we hadВ attachedВ so we could say we neglected those masses. In this particular case, the direction of net force points to the center of the circle, where a=v^2/r. The acceleration ( a )В of the object is directly proportional to the net force, and is inversely proportional to the mass ( m ).

In this lab, we verify Newton's second law of motion (uniform circular motion). We can say that our results are accurate and convincing. The last one (added 50 g) is much closer than the first one.

Our average calculated centripetal force when added the 100 g is very close to the measured centripetal force. According to our table of data and results, we can say that when the radius is kept constant and the mass increases, the centripetal force increases.

In this lab I learned how to measure centripetal force and how to properly use a vernier caliper. a mass, m, colliding with a mass, 2m, initially at rest. a mass, 2m, colliding with a mass, m, initially at rest.ДЈ. a mass, m, colliding with an identical mass, m, initially at rest.Дў. Do a theoretical calculation for О”K/K in a perfectly inelastic collision for the three situations:ДЎ. Find the percent kinetic energy lost during each collision. For each of the nine trials above calculate the kinetic energy of the system before and after theД¬ollision. On the results of your experiment? Explain.ДЁ.

Verification of the law of conservation of linear momentum. Find the average of all of the percent differences found above. Remove the 500 g from the second cart and place it on the first cart. Graph showing the position vs time for a typical collision. Place an extra 500 g on the second cart and repeat steps 3 and 4.

Calculate the momentum of the system the instant before andДЄfter the collision for each trial and find the percent difference. Repeat for a very small range ofДata points just after the collision. Record the slope (velocity) of this line. Avoid the portion of the curve which represents the collision. Is this a good approximation? Why or why not?ДЇor the velocity before the collision, select a very small range of data points just before theД¬ollision. The carts at the instant before and after the collision. To avoid the problem of dealing withДЇriction forces (Remember, we are assuming the system is isolated.), we will find the velocity of Velocity directly before and directly after the collision. time graph directly before and directly after the collision give the What should these graphs look like? Draw an example: Observe the position vs time graph before and after the collision. With the second cart (m2) at rest give the first cart (m1) a moderate push away from the motionДetector and towards m2. This will insure that they will stick together after theДЈ. Reasonable graph of the motion of the cart? Remember to be aware of unwanted reflectionsД¬aused by objects in between the motion detector and the cart. Observing the position vs time graph being drawn by the computer. Move the cart nearest the detector back and forth a few times while First, check to see that the motion detector is working properly by clicking the Collect button to
