Objective: The objective of this laboratory is to understand the relationship between force and acceleration. Hopefully, this lab will also get you thinking more about the relationship between different factors within accelerating systems.
Prediction: In this laboratory, you will be applying a constant force (using a constant hanging mass) to a system. For this an air cart will be placed on a level air track with a string attached to it over a pulley. A hanging mass will then be hung from the end of the string. Predict what the position, velocity and acceleration (versus time) graphs will look like if the frictionless air cart is given a small push toward the motion detector (away from the hanging mass). The air cart will first move toward, then away, from the motion detector due to the string tension.

Prediction Questions: The predictions provided on each lab handout are to help you prepare for the lab session. The questions will typically ask you to either do a calculation or think about a concept that will be used in the lab. Predictions: Answer the following prediction questions and turn them in at the beginning of lab. Each individual is responsible to turn in their own set of predictions (no group predictions please). 1.Predict what the position, velocity and acceleration graphs will look...

The sum of the forces on an object is directly proportional to
the mass of the object and directly proportional to the
acceleration of the object. The second law is expressed by the
equation: (1) F=ma
If the mass is in kg and the acceleration in m/s2,
then the force is in Newtons.
In (1), F is the net applied force, m is the mass of the object
on which the force is applied, and a is the acceleration of...

3 Force and acceleration (20 points) Two smooth rocks with equal mass sit on smooth ice, where friction is so little that we can ignore it. You apply a certain force, Fo, to one of the rocks, resulting in the rock accelerating at a rate 0.1 m/sec2. If the two rocks are tightly tied together by a string to make a single object with twice the mass of one rock, and you apply the same force Fo to one of...

Recall your experimental setup from Lab 05A: a constant force was applied to a disc by attaching a mass to a light string wrapped around a mass-less pulley and hanging the mass over the edge of the apparatus. In the lab, you used energy conservation arguments to derive an expression for the angular velocity of the disc after the mass had fallen a distance x. Your goal now is to use kinematics and dynamics to confirm your expression. Use the...

Figure 158-M5-3.JPG In one experiment you measured the acceleration of a glider that is floating on an air track while being pulled by a string routed over a pulley. By measuring the acceleration when the glider is moving towards the pulley and away from the pulley, you were able to determine the frictional force acting on the glider. Assume the total mass of the system (the glider, hangar and any additional masses placed on both) is 328.5 grams. If the...
