Relationship between Mass, Force and Acceleration: A Scientific Experiment

Centripetal force is a net force that acts on a body moving in a circular direction and is directed towards the center of the circular direction it is

1. Record: Select the BAR CHART tab, select Acceleration from the dropdown menu, and turn on Show numerical values. The bar on the left shows the magnitude of the acceleration, or |a|. The units of acceleration are meters per second per second, or m/s2.

4. Connect the Newton Scale to the cart and then drag the cart up the ramp, across the 30cm difference at a steady rate.

To result in a net zero force, the other vector would have to be of the same magnitude as the one shown but in the opposite direction. The stone pushes down on the ground with a certain force and the ground pushes up on the stone with an "equal and opposite" force. the normal force vector

Use a metric ruler to measure the displacement of the tip of the second hand every five

Force is equal to the mass of an inert object multiplied by the acceleration of that body

Using Vernier, we clicked collect while releasing the cart after motion detector starts to click. This was done moving the hand quickly out the path. Using logger pro, indicated which portion was to be used by dragging across the graph to indicate the starting and ending times. Then the linear button was clicked to perform the linear regression of the selected data. The Linear Button was used to determine the slope of the velocity vs. time graph, only using the portion of the data for times when the cart was freely rolling. We found the acceleration of the cart from the fitted line. Record the value in the data table. These steps where repeated 5 mores times. Measured the length of the incline, x which is the distance between the two points of the ramp. Measure the height, h, the height of the book(s). The last two measurements was used determine the angle of the incline. Raise the incline by placing a second book under the end. Adjust the book so that distance, x, is the same as the previous reading. Repeated these steps with 3, 4 and 5 books.

In our to be a Mechanical Engineer class we had to transfer a stuffed pikachu doll into the container (pokeball) down below. The pikachu doll had to be transferred on a trolley of our own design on a 52’ and 1” plastic coated 1/16” steel cable at a slant downward angle. If it is possible to close the lid do so. For the trolley the design specifications should be safe to use, easy to operate, it can’t be no longer than 32” and weigh more than 4 lbs, and lastly the device must be purely mechanical with no electronics, combustion, liquids, chemical reactions, or compressed

Describe how measuring masses of reactants and products can illustrate the law of conservation of mass.

While you are going up the first hill you will be traveling at a constant speed of 8 miles per hour. The machine in the roller coaster has to use a certain amount of work to get the mass of the people and cart up the first hill. Right before you start to spin down the first hill there will be gravity and acceleration pulling you down the spinning hill. Once you stop spinning while going down that first hill you will be at a spot right before the first hill where you will be experiencing terminal velocity. After you finish that loop you are gonna get pushed right up another hill and as you are falling down the hill you are gonna loop forward and be weightless while going through newton's 2nd law as you near the bottom of the hill. You will start going up another hill like the one on Track A and twist down in a corkscrew type way. During the twists you will experience very much centripetal force. You will go around another little turn like you did on Track A then instantaneous speed will be slowing you down right before you go back into the station.

5. What’s really meant is that the forces are the same but going in different directions as a mirror image of one another. So when one force is going for example 2 newtons in a positive direction, the same amount is going in the opposite direction.

Controlled Variable – Same amount of air resistant (stay in the same room), same surface of what the trolley is going to accelerate on, same trolley, have the string equally stretched out every time and same tick rate of the ticker timer. The controlled variable will be controlled to create a fair test.

Theoretically if there were no resistant (e.g air resistance, friction ETC) a down falling body on Earth would accelerate at the rate of 9.8 m/s^2, this is known as the gravitational acceleration. Theoretically the force of the downfall and acceleration for 500 gram would be 9.8 m/s^2 x 0.5 kg = 4.9 N. However in this prac as the force is greatly reduced by the resistant forces such as friction between the wheel and the table or the air resistant faced by the trolley and weight, the total amount of force was reduced.

The beam was loaded the mid-length in 2.745 lbs. increments up to 6.745 lbs. The change in clearance of every load step was measured and data was recorded.

When two objects get in contact with each other the force between them forms. Scientists call this force the frictional resistance, or friction. It occurs because of the imperfections in the surfaces of objects, the molecules of both surfaces interfere with each other creating a natural force between two objects. The friction opposes direction of motion of the object and is parallel to the surface on which the action takes place. The force and magnitude that are necessary to overcome friction can be calculated. Area of objects that is involved in the contact is disregarded when calculating friction.
