The objective of the experiment was to discover the effect of mass and radius on the centripetal force of a system and determine the mass of a hanging object using the discovered properties. Centripetal force is the culmination of multiple forces that act on a spinning system. By attaching a known mass and changing the radius on between a center post and the unknown mass, the unknown mass can be calculated. Likewise, if the inverse is tested, with a variable known mass and fixed radius, the unknown mass can be calculated. Centripetal force is caused by the interaction of the force of gravity, tension, and acceleration. In order to calculate the centripetal force, the equation Fc = m0•(v^2/r), where m0 is the mass of the hanging object, r is the radius between the center post and the hanging mass, and v is the velocity. In the equation v = 2πr/T, so that the equation can be manipulated to Fc = (2π/T)^2•m0r. To set up the experiment, a central force apparatus was calibrated and setup with a hanging …show more content…
Then, the weight hanger is removed, the platform is spun until the indicator bracket and disk realign, and the apparatus is timed for ten revolutions. To proceed, the radius is changed and the experiment is run identically until measurements are made for five different radii. For the second experiment with variable mass and fixed radius, the apparatus is set up similarly to the first experiment, but the side post stays at the same radius while the weights on the weight hanger are changed. Again, the indicator bracket and disk are lined up for each trial, the weight hanger is removed, and the apparatus is spun for ten, timed revolutions. Likewise, five different weights are measured. In order to calculate the unknown mass of the hanging
This question can be answered by having an understanding of centripetal acceleration and centripetal force. Centripetal force described as “the force that keeps an object in its uniform circular motion.”5 The centripetal force in the Greek Waiters Tray is provided by the waiter’s arm.6 Centripetal acceleration is described as “the acceleration needed to keep an object moving in circular motion.”7 The centripetal acceleration is provided by the plate of the Greek Waiters Tray.
The biomechanical principle stability for a pirouette is primarily concerned with the center of mass
to get an idea of how I would do my real experiment and what apparatus
Planning Firstly here is a list of equipment I used. Boiling tubes Weighing scales Knife Paper towels 100% solution 0% solution (distilled water) measuring beakers potato chips Cork borer. We planned to start our experiment by doing some preliminary work. We planned to set up our experiment in the following way.
= = = = The first step was to carry out some preliminary tests to establish the best set up for our apparatus.
used in the experiment. Spring constant The spring constant will be useful to confirm the relationship. It is a good idea. A simple force - extension experiment should be performed to get an accurate value for k which can be compared to the value of k in the final experiment. Amplitude: The amplitude of the oscillations should be kept constant.
The first thing my group did was confirm our method of taking data and who would be doing it as well as defining out independent and dependent variables. Since we would be directly controlling the net force we made that our independent variable which left the acceleration as our dependent variable because it was a factor that varying as a result of our net force. We weighed our cart with every single mass in it along with the string and the hook which turned out to be 1.97kg. We did not add anything else to our system after this to keep the mass of the whole system constant. Our setup was like this: a ramp was sitting on top of the table, parallel to it so it had no slant. On one end of the ramp, a pulley was attached. On the other side of the ramp, a motion sensor was set up so it faced directly down the path of the
In the experiment these materials were used in the following ways. A piece of Veneer wood was used as the surface to pull the object over. Placed on top of this was a rectangular wood block weighing 0.148-kg (1.45 N/ 9.80 m/s/s). A string was attached to the wood block and then a loop was made at the end of the string so a Newton scale could be attached to determine the force. The block was placed on the Veneer and drug for about 0.6 m at a constant speed to determine the force needed to pull the block at a constant speed. The force was read off of the Newton scale, this was difficult because the scale was in motion pulling the object. To increase the mass weights were placed on the top of the ...
The crucible and cover were placed on the triangle, and they were heated until they turned red hot. Afterwards, they were removed from the fire with the tongs and placed on the wire gauze to cool for ten minutes. Then, the mass of the crucible and cover was measured and recorded in the data
...e rider or the car. But as the train hits a turn in the track, it will want to continue going forward. The track will impede this from happening and push back at the rider and the car, pinning the rider to the side of the car. Although the rider will feel as if there is a force acting on them towards the outside of the curve, there is actually a force called centripetal force pushing towards the inside of the track. This lateral force is actually a force of 1-G, or the equivalent of lying down on your side.
“A roller coaster is essentially a gravity-powered train (2).” Gravity is the weakest of the four physical forces, but when it comes to roller coasters, it is the dominant one. It is the driving force and what accelerates the train through all the turns and twists. Gravity is what applies a constant downward force on the cars. The deceleration or acceleration mostly depends on the inclination of the angle relative to the ground. The steeper the slope is, the greater the acceleration, and vice versa.
Possible sources of error in this experiment include the inaccuracy of measurements, as correct measurements are vital for the experiment.
== 1. The flywheel was set as shown with the axle of the flywheel horizontal. A polystyrene tile was placed on the floor to avoid the impact of the mass on the floor. 2. The vernier caliper was used to measure the diameter d of the axle.
...e could add the mass piece without having them fall off. At the time of the experiment, this was not seen as a threat to our results.
To explain these models, the forces as well as velocities acting on the ball are described mathematically. The three most important forces considered here include the force due to gravity, force from the spin, and the force due to air resistance.
