Homework Answers
1.) Yes this assumption is valid because the magnitude of friction force is very low in comparison to other acting force hence we can neglect it's effect on the whole system and it will not bring any significant change is the final result
2.) Yes this assumption is also valid because magnitude of moment of inertia is very low hence we can neglect it and it will not bring any significant change in the final result

2) Moment of Inertia for Multiple Objects We have loosely defined the moment of inertia as the difficulty or resistance encountered when trying to change an object's rotational motion. What if we were trying to rotation a combination of objects? a. Suppose you have a very light cloth pouch, and you place an apple of mass M=200 grams in it. You tighten up the satchel and start to swing it around, with the string in the satchel making a length...

I need help with a kinetic friction lab... We set up a level cart track with a motion detector at one end and then gave a wooden block a push on the track towards the motion sensor to measure the deceleration of the block. How do I calculate the kinetic coefficient using our measured results? The block weighed 131.1g. The slope of the velocity graphs for our 3 trials were 3.73, 2.72 and 2.9 m/s/s.

Lab 8 Assignment: Moment of Inertia 1) Moment of Inertia for Different Systems The resistance to rotational motion change is more involved than for linear motion because it not only depends on what the mass is, but also on how that mass is distributed about the axis of rotation. The farther away from the axis the mass is distributed, the greater the moment of inertia. Using this simple definition, for each of the following pairs of objects, determine which of...

Constants| Periodic Table The graph below shows a measurements of the angular velocity from the rotary motion sensor along with a line fit, as taken by DataStudio. The hanger mass was 14.5 g and the pulley radius is 14.9 mm. An object different from either the ring or the disk was attached to the turntable. From the information in the graph and what is given above, calculate the moment of inertia of the rotating turntable plus the object attached to...

Practical 3: Rotation due to an External Moment - Pre-Lab Preparation Rotation due to an External Moment: Pre-lab Preparation In this practical exercise you will investigate the angular acceleration of a disc about its centre of mass due to an applied moment, and determine the moment of inertia of the disc. Write down the equation...

Cal Cart A cart E -trock In this experiment, we use a simple apparatus to test the theorem of energy conservation. Figure illustrates the system to be studied. A cart of mass m at the end of an inclined track is held at rest by hand at point A. When you release it, the cart rolls down on the inclined track until it hits the bumper attached Lebo to the bottom of the track. A motion sensor at the top...

INVESTIGATION 10 ROTATIONAL MOTION OBJECTIVE To determine the moment of inertia I of a heavy composite disk by plotting measured values of torque versus angular acceleration. THEORY Newton's second law states that for translational motion (motion in a straight line) an unbalanced force on an object results in an acceleration which is proportional to the mass of the object. This means that the heavier...
