Lab Activity 4 : Centripetal Force

Set the radius to 2.0 m, the mass to 1.0 kg, and the velocity to 10.0 m/s.

Loosen the retaining screw and adjust the horizontal arm to the dimple that produce the 2nd largest radius between the spinning mass and the rotating shift. Allow the spinning mass to hang straight down, without being connected to the spring. Position the pointer directly below the tip of spinning mass and secure the pointer to the base. Use the scale located on the base to determine the radius, r, of the pointer from the rotating shaft. Record this value onto Data Sheet A. The experimental uncertainty in r is estimated to be the width of the spinning mass tip – approximately 0.2 cm.

Circular motion is one of the fundamental building blocks for understanding the physical world because it is so common. This interactive lets you examine the basic ideas of kinematics and forces for objects moving in circular motion.

What is the question asking you to identify? This question is asking to clearly identify centripetal force.

b. Describe the direction of the force and the meaning of the negative sign in the acceleration value.

2. Click the radio button for 4 objects and run the simulation until the purple planet (body 2) has made one complete orbit (one year).

Since most loops are shaped similarly to a circle, then we can take the radius of the loop to find the centripetal acceleration experienced by the rides going around the loop using the following

The minimum speed required to make it around the loop successfully can be calculated using the formulaFc=(mv^2)/r. However in order to get the centripetal force required first we must calculate the force of gravity acting downwards on the cart when it is at the top of the loop calculated by the equation, F=mg.

* The relevance of this experiment is similar to understanding a real airplane. Paper airplane models are derived from an actual plane these days. The design of an airplane has so much to do with distance, hang time, speed, and many other factors. Understanding the models I have chosen to make help me

Weights acting on the mass hanger were removed to observe more loops that were able to form. Again, the length of the string, tension and number of loops were determined and recorded. The wavelength (w) was calculated

Step 9: Because we measured the lengths in centimeters rather than meters, we need to calculate are ‘g’ value into m/s2 so we can compare it to the SI unit for acceleration due to gravity. (Eg. 981.4/100 = 9.81 m/s2)

For the first method, it is necessary to know the linear mass density of the string (μ), which can be found by taking the total mass of the string (M), and dividing it by the total length of the string (L_total). However, for this experiment, the string will be stretched to various lengths depending on how much tension force is being applied by the hanging masses from the pulley. Also note that there was no excess string hanging limply from the back of the pulley. Therefore, the linear mass density

The orbital accelerations represent a shift in the orbital positions of the Galilean satellites Io, Europa and Ganymede of 55 km, -125 km and -365 km over the 116 years respectively. The fit astrometric residuals range essentially between 0.02 and

The objectives achieved in the experiment were attributed to determining how a hanging mass on an object can determine the speed and also the acceleration. The experiment consisted of a pulley system that was created using an air track and glider. The system also

Theory states that T and d are related by the equation: T2 = kd3+ (4π2 l)/g where g is the acceleration of free fall and k is a constant.
