## Momentum

Measure the mass and radius of the aluminum disk. This T2 on the M2 side. This would be the adjacent side M1 G cos Î¸. Down is our positive y direction because we are here and we called down the positive y on this side. This system is convenient for studying motion under constant acceleration because we can make the motion much slower, and easier to measure, than if we simply allowed objects to fall freely under the influence of gravity. B move faster along the rope.

If the fan is blowing in one direction, it will make the cart accelerate, and if there are two fans blowing in opposite directions, the cart will remain at a constant velocity because it is a balanced force. And we have M1 G. Angular Acceleration using the data from Part A. Let us take a look at another one. In this case I see that we are going to be going down on the M 1 side so I would probably draw an arrow like this and I am going to call that my positive y direction.

You can always change what data is shown on a graph by tapping on the y-axis label. Be sure to record the masses used for each trial. Mount the rotary motion sensor and support rod on the table that have sufficient space for the masses to move up and down on either side of the rotary motion sensor. For part E, 1 and 2 for masses. This will be accomplished using a rotary motion sensor connected via Lab Pro Interface to a laptop computer.

Also that if the mean radius R increases, so will the torque. Mass keg X Axis c. What idealistic assumptions or other sources of error may have affected your results? Be sure that the interface is properly attached to the computer, and that the power supply is plugged in. Depending on which category you belonged to would dictate the color of clothes you wore. Let us do our free body diagram from as 2 here. This tension will be measured by a force sensor attached to the top of the cart.

Now place a 20-gram mass on the end of the string passing over the pulley. From the graph that gives the velocity vs. The timing will start when the 1st domino is hit by a metal ball and it will stop when the last domino falls completely. You should now be looking at graphs of position vs. Then we will calculate the theoretical inertia using the moment of inertia equations for a disk and a ring. We are going to define that is our positive y direction tensions are the same T and T and let draw our free body diagrams.

## The Atwood Machine

We will see you again soon and make it a great day everyone. The mass of one side is gerater than the mass of the other, meaning the heaver side has a greater weight force mg acting upon it equating to a greater accelearation. Discuss whether or not and how well or not the graph of torque vs. A117: use this input form: x axis label include units : y axis label include units : Check this box if the fit should go through 0,0. For our second mass, M2 down will be our positive y direction and we have tension upwards and M2 G down. Determine the line of best fit.

Length m X- axis b. As our total mass increased, the acceleration decreased. Here we will have M2 and T2. Forces on Inclined Planes Notes should include: Defend: Dynamics is defined as the study of the effects of forces on matter. These four categories in order of superiority are: Commanders of the Faithful, Eyes, Angels and Guardians. A If the total mass is constant, and mass is moved from one side to the other, the acceleration would stay the same. If I pull the a out of those is I add them together.

Just slight variation on the same theme. Factoring G Ã— M2 - M1 sin 30Â° must equal a Ã— M1 + M2. Part A â€” Torque vs. Masses are hung on a light string attached to an ideal mass less pulley has shown a diagram here below left. Discuss the results of the experiments concerning conservation of angular momentum. Hopefully, that gets you a good start with Atwood machines. Measure the dimensions and masses of the rod and brass collars.

Copernicus and then Galileo were the first to dispute Aristotle's thought on movement and in doing so they developed the first thoughts on inertia. Standards Correlations Choose a standard to view standards correlations for this experiment. And finally, our highest acceleration A. Be careful to not contact the object that you drop after it hits the disk. Put another 2kg mass on the top plate. A car or glider travels on a cushion of air provided which reduces friction. Both sets of electronic data will be collected and analyzed by a LabQuest2 device.

Attach the pulley to the end of the track and adjust the height of the pulley to match that of the hook of the force sensor. A complete report 50 pts : pages in this order q Data Tables 8 q Torque vs. The result of changing only the total mass and not the force making it accelerate or other variables gives you the inverse relationship between total mass and acceleration. Physics with Vernier See other experiments from the lab book. For D, we have initial mass m 1 is 1, M2 is 4, so the magnitude of the net force 4 -1 is 3 Ã— 10 is going to invest 30 N. A a king-size pillow B an automobile battery mass A kilogram is a measure of an object's D all of these Compared to a 1-kg block of solid iron, a 2-kg block of solid iron has twice as much A inertia. I am Dan Fullerton and in this lesson we are going to talk about Atwood machines.
