It can be said that the impulse acting on an object is equal to the change in momentum of the object. In mathematical form, momentum lab report, this can be written momentum lab report. From eq, momentum lab report. When two objects collide with no external force acting on the system, the total initial and final momenta of the system will be equal. If the total kinetic energy KE of the setup is conserved, it is said that an elastic collision has occurred.

The total KE of the system is the scalar sum of the KE of all the moving parts. An inelastic collision is defined as a collision when the total KE is not conserved. In general, an inelastic collision occurs when the objects collide and stick to each other. In the case of one dimensional motion, that is, all motions occur along a line, the conservation of momentum states that.

The final KE can be related to the initial KE by a series of steps involving eqs. Prediction: Draw a quick sketch of the graph of velocity vs. Make a prediction about a graph of the force acting on the cart vs. User Tools Login. Site Tools, momentum lab report. Table of Contents General Physics Experiment 7. To observe conservation of momentum in collision processes.

They must be able to velcro together they should not magnetically repel each other. Connect the force sensor into analog channel A of the Signal Interface, Make sure the force sensor switch is in the 50N range setting. Place the Force sensor on the table, momentum lab report, and with no tension on the force sensor, click on Set Current Value to Standard Value to set the 0 N force.

The tension force equals the weight of the mass, which is 0. Enter 4. Place the Force Sensor horizontally at the other end on top of the wooden block so that the spring on the cart can hit momentum lab report force momentum lab report hook. Place the cart on the track with the spring unhinged and facing the force sensor Figure 2. Make sure the track is level so that the cart does not accelerate in either direction.

Let the cart bounce off the force sensor and return, stopping it before it hits the motion sensor. Click and drag to highlight a few points just before the collision the collision occurred where the velocity data jumps down. Record the mean. Click and drag to highlight a few points right after the collision. Record the mean, including the sign. Don't forget to make the sign of your velocities appropriate for the direction that your cart was traveling!

Calculate the change in momentum of the cart during the collision be careful of signs. On the force vs. Click on the rescale icon. Discuss with your partner how your graph would be different if you did not have the spring plunger to bounce the cart assume you have the same start velocity for both runs and that both collision with the sensor have the same energy loss.

Hint: consider an egg toss. How do you keep the egg from breaking while you catch it? Increasing one factor decreases another. Place a motion sensor at the left end of the track. Plug into the Science Workshop Interface with the yellow plug in channel 1 and the black plug in channel 2.

Place a motion sensor at the momentum lab report end of the track. Plug into the Science Workshop Interface with the yellow plug in channel 3 and the black plug in channel 4, momentum lab report. Turn the dial on the side of the motion sensor so that it is pointing slightly down. Turn the button on the top of the motion sensor for the wide range switch momentum lab report to the right.

Place Mass 3 on Cart 2, calculate the total weight and record as Mcart 2. Make sure that the spring is latched on the cart so that the velcro sticks together Figure 5. Click start, then push cart 1 towards cart 2. Stop the combined carts momentum lab report they hit the motion sensor. You should see data from both motion sensors, they should have a straight portion, momentum lab report, then a sharp jump downwards and then continue on straight.

If the data from either motion sensor is not very straight either adjust the motion sensor dial or switch the motion sensor setting to near turn the switch to the left and try again.

Repeat until you get fairly straight data. Because there are two motion sensors, the sign of the velocity might not be consistent, momentum lab report. We are going to choose the positive direction to be from Motion sensor 1 to Motion sensor 2.

Then any velocity recorded from Motion sensor 1 will have the correct sign momentum lab report any velocity recorded from Motion sensor 2 will have the wrong sign, momentum lab report. On the data from Motion sensor 1, click and drag to highlight a portion of the straight momentum lab report right before the crash the downward spike. Record this in Table 1 as v i for Cart 1.

On the data from Motion sensor 1 and Motion sensor 2, click and drag to highlight a portion of the data right after the crash, momentum lab report. Find the average of these two values and record as v f in Table 1, momentum lab report. Remember that the sign of Motion Sensor 2 is wrong it reads negative, correct it and make it a positive value.

Complete Table 1 by calculating the momentum before and after the collision. Also calculate the Kinetic Energy before and after the collision. Call this the ideal ratio. Calculate the percent difference between the measured and ideal ratios. Place Cart 2 at rest in the middle of the track and place Cart 1 near the left motion sensor. Click start and push Cart 1 towards Momentum lab report 2. Stop each cart before it hits the motion sensors.

If the data from either motion sensor is not very straight adjust the motion sensor dial and try again. Click and drag to highlight a portion of Motion Sensor 1 data before the crash. Record as v i for cart 1, in Table 2, momentum lab report.

Click and drag to highlight a portion of Motion Sensor 1 data right after the crash, momentum lab report. Record as v f for cart 1, in Table 2.

Click and drag to highlight a portion of the Motion Sensor 2 data right after the crash. Record as v f for cart 2, in Table 2. Remember to reverse the sign of the velocity. Complete Table 2 by calculating the momentum before and after the collision. Momentum lab report sure one of your carts has a spring plunger on it, and place one accessory weight on Cart 1. Make sure that the spring is latched on the cart so that the velcro sticks the two carts together.

Attach the two carts together with the Velcro and place in the center of the track Figure 7. Press start and at the same time, using a pencil, push the button on the carts with the spring so that the spring unlatches and the carts explode away from each other. Make sure to stop the carts before they hit the sensors. Click and drag to highlight a portion of Motion Sensor 1 data right after the explosion.

Record as v f for cart 1, in Table 3. Click and drag to highlight a portion of the Motion Sensor 2 data right after the explosion. Record as v f for cart 2, in Table 3. Because the carts spring away in opposite directions, their velocities will have opposite directions. This means that one will be positive while the other will have a negative value. Discuss with your partner how the energies of this collision are different than the elastic and inelastic collisions.

Elastic collision with CART 1 at rest Place cart 1 at rest in the middle of the track and place cart 2 near the left motion sensor. Click start and push cart 2 towards cart 1, momentum lab report. Stop each cart before it hits the motion sensor. Record as v i for cart 2, in Table 3, momentum lab report. Complete Table 3 by calculating the momentum before and after the collision. Names: Put 'scribe' beside the name of the person writing the abstract, conclusion, etc.
