## The Centripetal Force Requirement High Compared to a typical science class, please tell us how much you learned doing this project. The quantities measured in this lab are somewhat sensitive and require you to take care in making measurements. However, check to make sure that the marble stays roughly in the middle, between the two layers. Centripetal force is a force that must be constantly pulling us towards the center of the loop, not just at the bottom or top of the loop. What horizontal force must be applied by the worker to maintain the motion? Mm of the nylon string. Also, if more tr ials for more radii were conducted, the accuracy could have been improved.

Test 2: Rotating Table The measurements taken from Test 2 were recorded and placed onto graph 2. Conclusion This was a very successful lab overall. A short quiz will follow. There may be miscounting in the number of circulations, because the time for 50 revolutions is quite long and students may be distracted. Since error in this experiment can be either positive or negative it is useful to use an error formula that examines error squared as expressed by du 2.

## General Physics Lab 6: Centripetal Acceleration Set the number of washers to five or something else; it's not important. Newton discovered that to get an object to move, the object must experience a force that makes it move in a certain direction. Typically one uses a radial-tangential coordinate system shown in the figure above. Remember that it is customary to put the quantity you change force, in this case on the horizontal axis, and the quantity that changes by itself speed on the vertical axis. Discuss your plans with your partner and your lab instructor. The period of swing decreased as the period T increased.

You should have several holes on the edges to attach strings. Length m X- axis b. Science Buddies materials are free for everyone to use, thanks to the support of our sponsors. Procedure Materials Projectile launcher Marble Two measuring sticks Tin foil Pencil Set the angle of the projectile launcher to 30 degrees make sure that the bottom of the launcher is even with the desk. Step 5: Play around in this way for as long as you like. Step 3: Put the plastic cup of water on the platform and hold the platform cup by the strings.

## Centripetal Force Experiment: Lab Analysis The experiment was carried out with the range of L 0. From data table 2 construct a graph of period T Y axis vs. So if you haven't already, it's time to pause the video and get started. In the case of the ball on a string going around in a circle, this force was the tension of the string. What is the tension in the rope? It is made up of the sum of the angular momentum of the body's segments. You have felt this phenomenon when riding in a car.

## Centripetal Motion: Physics Lab When the stopper is in circular motion it has acceleration because its direction is constantly changing. Could it be the force of the seat itself that is holding us in our seat? In fact, if the forces are balanced, then an object in motion continues in motion in a straight line at constant speed. Or adjust those numbers - again, just get an adequate range of values. Step 4: Starting carefully, swing the cup of water back and forth like a pendulum. Virtually every object that you see around has been mechanically engineered or designed at some point, requiring the skills of mechanical engineering technicians to create drawings of the product, or to build and test models of the product to find the best design. The mass remained stationary during the trials.

## Centripetal Force Lab Earth's motion about the sun e. » » » The Centripetal Force Requirement The Centripetal Force Requirement Uniform circular motion can be described as the motion of an object in a circle at a constant speed. In your lab notebook, make a table like this one to record your observations and data. Assuming constant breaking force find: 1 the magnitude of the breaking force, 2 the time required to stop. We measure the radius, mass of the stopper, and centripetal force as before. The coefficient of kinetic friction between the brake and rim is 0. This can be demonstrated by carrying a tennis ball upon a flat, level board.

## Centripetal Force Lab Report Essay Now, make sure the string is fed through the tube with one end tied around the stopper and the other end tied around the paper clip, with the cord clamp somewhere in between on the string. For each of these three graphs,. Data Trial Hanging Mass g Mass of Stopper g Total Time s Radius m Varying 1 100 45. The formula for tension is found by isolating it to one side of the equation presented earlier: When the force of gravity is counteracted, possibly by a horizontal spinning table, then the force of tension on the string is only due to the centripetal force and the second term is equal to 0. So as the radius increases and mass and velocity remain the same, the centripetal force will decrease. This is illustrated in the animation on the left below. Repeat for several different weights.

## Centripetal Force Lab Report Research Paper Example : momentumclubs.org Which force is the centripetal force when we ride in the loop-de-loop? This does not mean that constant speed always indicates no acceleration, however. When the string breaks, however, the stopper will move at a constant elicit therefore producing no acceleration. This cup will be your centripetal force generator. There should be between four and six readings. Abstract What keeps you in your seat of a giant loop-de-loop roller coaster? You can keep the radius of the circle constant with a little practice by keeping the upper clip a fixed distance below the glass tube while whirling the object. Fold over the tape so it is on the outside and inside of the cup, but not blocking the holes.

## Centripetal Motion Our universe is full of matter and energy, and how that matter and energy moves and interacts in space and time is the subject of physics. Two experimental conditions were measured using 1 a simple pendulum and 2 a rotating table and the force of tension exhibited on a string was measured in both cases. The mean value for velocity will be used in equation 8 to calculate the force of tension that should be exhibited by the string. Suppose in our initial example that a car is traveling through a curve along a flat, level road. You must spin the cup hard and fast to get enough centripetal force for the marble to move! The data was then analyzed graphically and mathematical calculations were performed on the graphical data. A freebody diagram of this situation would look very much like that of the block on the end of a string, except that friction would replace tension. An equation can be used to represent the relationship between centripetal force, mass, velocity, and the radius of the circle.
