Aim: How does the circumference of 5 different sized ball bearings affect the time it takes to reach the end of the V-ramp? Justify: The reasoning for looking at this experiment was when I was in the car going down a steep hill, and was wondering if the bigger the wheel of the car with the same mass if I would reach the bottom faster than if I had smaller wheels on the axel. Hypothesis: The larger the circumference of the bearings, the faster it would roll down the v-ramp as the force is pushing behind the larger amount of surface as well as completing one full turn rather than smaller turns to make a whole. Independent variable Dependent variable The circumference (cm) of the ball bearings. Measured time to calculate speed. Distance/Time …show more content…
Keep the ball bearings inside of the plastic container and not pour them out all over the work bench. Method: Place all of the following onto your work bench: 5 different sized circumference ball bearings inside 1 plastic container (so they do not roll all over the bench, onto the floor or down the sink), a stopwatch, 15cm string, a black texta and an electronic balance. Lean the 2.17 m v-ramp on the side of the bench on a diagonal so the other end is being blocked by something sturdy such as a wall or side of another bench. Place the container onto the scales and take out all five of the bearings and hold them in your hand whilst pressing the tare button on the electronic balance to take it to zero. Place one of your bearings to see the mass, record it and take it out. Repeat this for each individual bearing making sure to press tare every time to receive an accurate …show more content…
Let go of the ball and start the timer, when it hits the bottom stop the timer. Repeat this 3 times for each of your other ball bearings to minimize any measurement errors. After this you need to measure the circumference of each ball bearing. To do this hold one end of the 15cm string and wrap it around the ball once till the end meets with the string again. Take your black marker and draw a dot or a line so that it is visible when you measure. For accurate measuring do this one more time. Take the piece of string and measure it against the 1 meter ruler (a 30cm ruler will do just fine) and repeat for the other 4 ball bearings. Qualitative Results: When releasing the ball bearing it was really hard to tell the difference in time between all 5 ball bearings.

After the rinses, close the stopcock and fill the buret up to the 0.00mL line with NaOH. Quickly, open the stopcock to fill the tip of the buret and then close the stopcock. Record the initial volume of the NaOH to the nearest 0.01mL.

Baseball is a fascinating sport that is exceptionally fun to play. This assignment is all about understanding the physics of a few key aspects of this sport. One might ask what physics could have to do with baseball? Like most sports baseball involves physical motion. Baseball encompasses all three planes of motion through throwing, hitting, and fielding. All of the classical laws of mechanics can be applied to understand the physics of this game.

On Tuesday in lab, we wanted to measure the velocity and acceleration of a ball rolling down an incline. To do this, we made our table have an incline by putting wood blocks under two legs of the table. We placed meter sticks on a table so we could determine the distance the ball traveled for a certain amount of time. We placed the ball at the 0cm mark on the meter stick and let go of the ball so it could roll down the table. To make our results more accurate, we videoed the ball rolling down the table with a stopwatch on our phone following the ball. We then went through the video and paused it at every 10cm and recorded the time it took for each 10cm interval from 0cm to 150cm. We did this experiment with 2cm, 4cm, and 6cm inclines to show
They use a special kind of rubber called butyl rubber. A machine helps to write on the balls to put the letters on it. Some balls are made with higher quality thread.
Roller screws are accustomed remodel rotary movement into linear movement and the other way around. The bearing components are threaded rollers positioned between the screw and therefore the nut. The massive variety of contact points permits roller screws to support terribly high loads. The roller screw is comparable to the ball screw with the distinction that the load transfer components are threaded rollers. When put next to standard ball screws, have the subsequent advantages: the most advantage of roller screws is that they need an outsized variety of contact points to support the load with higher permissible static and dynamic load capability. Due to the larger variety of contact points the bearing perform is ensured by uniform spreading of load over the threaded rollers rather than balls just in case of ball screws. It's higher mechanics and dynamics in operating condition, generates less vibration and lower noise. The transmission exactitude of PRS is higher and may add a lot of more durable condition. Because to these compensation, a lot of analysis on roller screw has been administrated, and therefore the roller screw has been utilized in the medical, aerospace, military, assembly, Food and drink, Plastics, textiles and machine tools industries.

Check if there are any leaks especially around the stopcock, the valve at the bottom of the buret. When it comes to calibration, it is calibrated by transferring water into an Erlenmeyer flask and weighing it using an analytical balance. This is done for two (2) trials, each with varying amounts of water. Erlenmeyer’s mass is pre-recorded before transferring water from the buret. The volume delivered by the buret is considered the apparent, which means evident, volume. Before starting another set, the flask should be clean and dry to avoid any error. The water inside the flask will add the volume to be transferred thus making the mass of water higher than what it should really be. The mass of water obtained thru weighing by difference would then be multiplied to the buoyancy of water at the recorded temperature which will then be the corrected mass of the water. The corrected mass of the water is then divided by the density of the water, at the same temperature, and will be considered as the true mass. Correction value can be obtained by solving for the difference between the true volume and the apparent volume. Some of the correction value computed are negative and it only means that there is an error that occurred. One of the possible errors in most volumetric glassware’s is reading the wrong volume. Volume must be read based on the lower meniscus at eye

The independent variables in this experiment are the height of the ramp, the length of the ramp, the surface of the ramp, the weight of the marble, the size of the marble, and the surface of the marble. The dependent variable is the distance the ball rolls. The controlled variables are the starting position of the ball, the angle of the ramp, and the surface of the floor. Units: The height of the ball from the ground, the height of the ramp, and the distance the ball rolls will be measured in centimeters (cm).
