These weights hang off the sides of the wheels and pull on the string at different angles, the objective is to find the point at which all the weights pull on each other so the center of the string is in the center of the force table. This was found in the lab by slowly adding weights till the right mixture was found. The forces are recorded and then shown through vectors. Adding the Vectors up shows that you have a system of equilibrium or not, depending if there is a gap between the first and last vector. The results came out to be complete vectors with the corresponding degrees of the angles with we experimented on.
Step two you will want to get the power supply mounted into the case. What you will need to do is take the power supply out of the box it came in. Then you will need to place it in the power supply spot on the case. It should be an opening on the top or bottom of case. Once you have found the spot where the power supply is going to be mounted, you will need to use the 4 screws that came with the power supply and screw it down in place.
The following equation represents this relationship where k denotes the spring constant or stiffness of the spring, F=-kx Since x symbolizes the displacement or change in the length of the spring the above equation can now be surmised in the following manner, F=mg=-k∆l This new form makes it evident that a linear proportion exists between the plot of F as function of changing in length, ∆, thus confirming the spring does in fact obey Hooke’s Law. This enabled the group to determine the spring constant k. B. Derivation of Equations Definitions To gain a better understanding of the terms used here
I would then crimp the ferule barrel twice, once at the connector side and again at the jacket side. I would then remove it from the crimping tool and examine it. I would check to see that the connector is
Hold the cart so that its rear axle is learned in 74, releasing the cart from notch A results in the fastes cart speed. Release the cart, and observe what happens. Measure the distance that the block moved down the track. Record the data as trial in your table. repeat steps 3-5 fourmatines and record data as trails 2-5.
This is called oscillating, when an object is undergoing periodic motion. To fully understand periodic motion we must first understand the concept of equilibrium and the two types. The first type is stable, when an object is in stable equilibrium any displacement of this object will result the object to try to restore itself to its original position. As stated in our lab manual, “For example, a weight hanging on a string is in stable equilibrium when it is at its lowest point. If the weight is pushed to one side, gravity will again try to pull it back to the lowest point.
AP Physics C Lab Report i. Purpose: To investigate the relationship in Newton’s Second Law ii. Materials: Pasco track and cart, endstop, pulley, string, washers, lab pro with motion detector, logger pro iii. Procedure: 1. Assemble the materials as shown in the diagram to the left.
2) The larger moveable knife edge was then clamped to the pendulum, at a small distance (1cm) above the centre of mass. 3) The distance h was then determined from the centre of mass to the axis of suspension. 4) The mask was then attached to the pendulum. 5) The light gate was then connected to the digit-metre and adjust its height and position relative to the mask to allow the period T, of the pendulum to be measured repeatedly. 6) The procedure was then repeated for larger values of h, until T has passed its minimum value.
28 October 2008 Introduction: Static and kinetic friction are forces that are a result of two surfaces in contact with each other. Static friction is the force that must be overcome to cause an object to begin moving, while kinetic friction occurs between two objects in motion relative to each other. The kinetic friction force, Ff, kinetic, is defined by Ff, kinetic = μkFN, where μk is the coefficient of kinetic friction and FN is the normal force acting on the object. The maximum static frictional force Ff, max static, is defined by Ff, static = μsFN where μs is the coefficient of static friction and FN is the normal force on the object. The maximum frictional force that must be overcome before movement is able to begin is μsFN.
The motor torque Tm (Nm) can be approximately modelled as Tm = K I, where K is the DC motor torque constant and I is the motor current (A). The Mechanics The model we are dealing with is a simplified version that neglects the rotational inertia of the wheels and other components of the motor system. The torque on the wheel is directly proportional to the motor torque Tm therefore T = Tm = K I can be directly calculated. The forces we will be dealing with are; the forward propulsion force (F) generated by the rear wheels, the gravitational force (W = M g) and the drag force due to friction (Fd). Mathematical Relationships The relationship between acceleration, velocity and distance will help us to model the performance of the car.
