[This experiment used a weight at the end of a string along a track. The track had a cart that was attached to the string. Different weights were put at the end of the string that was hanging over the ledge. Multiple trials were done. We took times of how long it took the cart to travel from point A to point B as it was pulled by the weight at the end of the string. Additional trials placed weights on the top of the cart and measured the amount of time it took to travel point A to point B]
Compare the acceleration of the cart measured over different distances. Should the acceleration remain the same or should it change? Explain your results.
No need for you to compare, just tell me what it should be and why.
Compare the acceleration of the cart with no weights, with one and with 2 weights. How does the acceleration change as M increases? Why?
No need for you to compare, just tell me what it should be and why.
What happens to the acceleration of the cart as you increase the mass on the end of the hanger? Why?
Please explain what should happen and why. Be specific.
Would this experiment have worked if the track were not level? Why or why not?
Please explain what should happen and why. Please be specific.

madikicd! to the Atwood's 'machine used in this experiment 3. In principle, attaching heavier weights should cause the cart to accelerate more quickly. Why is this the case? 4. If the weights hanging on the mass hanger in this experiment were left with constant mass, how would adding additional weights to the cart itself affect the cart's acceleration? Explain.

Why is it okay to neglect friction in this experiment? Justify your answer with your calculations of percent differences. This experiment involved a cart gliding on an air track (constant mass, and acceleration - measured time it took cart to move at different distances AND different masses and the resulting acceleration - measured time it took cart to move at a uniform distance). Percent differences were calculated for acceleration and mass.

Experiment: The force required to stretch an elastic is measured, along with the displacement of the elastic. The elastic is then used to launch a cart on a low friction track and the motion of the cart is analyzed. The experiment is repeated for a total of 5 trials. I need to draw a graph of kinetic energy of cart as a function of energy transferred to elastic. The energy transferred to elastic is elastic potential energy, given by E=1/2Fx....

please choose the correct answer, thx
One Dimensional Motion: For the acceleration due to a falling weight, what would happen if the hanging weight hit the ground before the cart passed completely through the The cart would stop accelerating at that point and move at a constant velocity, so the measured acceleration would be larger than expected The cart would come to a complete stop and the measured acceleration would be meaningless. The cart would stop accelerating at that point...

We did a lab where we leveled a horizontal track and used a massless frictionless pulley system with a weight to pull a cart and measured the potential vs kinetic energy of the closed system to find a slope of -1 when graphed. Why is leveling the track so important? How and why would your results be affected if the track were not level? If we did the experiment again and at the time that the cart is being pulled...

Cart on an Incline plane. Start up the Dynamics Track apparatus. Set the µKS? # stepper to zero (µk = 0.12 and µs = 0.18 by default). Please notice that the dynamic track has a feature to be tilted by dragging when the mouse cursor is in the colored part of either end of the track. The message box informs that the track can be tilted up or down. With the brake off, turn on the friction pad and put...

2 Experiment: In the experiment conducted, the mass of the counter weight M was chosen to be 50.0 +/- 0.1 g The mass of the rubber stopper was measured to be 12.0 +/- 0.1 g The stopper was spun at five different values of the radius (measured with a meter stick). For each value of r, the time to complete 10 full revolutions was measured with stopwatch. The following data was collected: 40.0 60.0 80.0 100.0 (cm) 1) 120.0 10.74...

10. Move the Motion Sensor. Place the Motion Sensor at the bottom of the track pointing up the track. 11. Check the Motion Sensor. Start with the cart at least 50 em in front of the sensor. Practice pushing the cart up the track so the cart doesn't go over the top of the track and stopping the cart before it gets within the 50 em of the sensor. Start the sensor and push the carit up the track. Stop...

Move Along Slope Track: 1. How do the general shapes of your descriptions and experimental position-time, velocity, time, and acceleration-time graphs compare? Were your expectations borne out by the experiment? Explain why or why not. 2. Does the sign of the acceleration on the experimental acceleration-time graph make sense? Use the definition of acceleration to help answer this. 3. Are the averages determined by the two methods above consistent? Use the uncertainties derived from your data to make the comparison....

By wiggling one end, a sinusoidal wave is made to travel along a stretched string that has a mass per unit length of 22.0 g/m. The wave may be described by the wave function y 0.20 sin (0.90x-42) where x and y are in meters and t s in seconds. 1. (a) Determine the speed of the wave. Is the wave moving in the +x direction or the -x direction? b) What is the tension in the stretched string? (c)...
