Physics Lab Report
Statement of the Problem:
The problem that was arisen in Problem #5: Motion up an Incline was in reference to a change in acceleration in both an uphill and downhill motion. The question on hand was whether or not the acceleration was the same going uphill as it was downhill or different from each other in both directions. To obtain a secure conclusion this experiment required the use of a frictionless cart, an inclined ramp, motion sensor, meter stick, and assistance of computer programs. These tools help us to achieve/correct our predictions by giving us precise information about the acceleration of the cart in both the up and downhill direction.
Prediction:
My prediction for Problem # 5 was how I felt that the acceleration of the cart would be equal but opposite to each other on the way up and down. As the cart is going uphill it would have a negative acceleration (see notebook for rough sketch of graph) because it’s slowing down and eventually going to return back to the bottom. As the cart is going down hill it is working with the acceleration making acceleration positive in a quantitative sense.
Data & Results:
The lab for Problem #5 was conducted in a pretty simple manner. Since are main goal was to see if acceleration were the same on the way up as it was down we just had to do a couple experimental runs by launching the cart up the hill, allowing it to reach its max distance up and then come back down. While doing the previ...
Whether zipping along a winding trail, flying through the open flats, or powering up a steep hill snowmachines and the rider need to use physics to stay in control of the machine and themselves. The main compenents are the track, engine, skis and riding.
1) Speed of the Marble: Speed = distance traveled by marble / time from clamp A
Our project required our car to go at least 3 meters. Our initial trials were successful because our car went 7,8, and then 9 meters. The car went 7 meters in 8 seconds with a speed of 0.875 m/s. It went 8 meters in 10 seconds with a speed of 0.8 m/s. It finally went 9 meters in 12
Question/Purpose : The purpose of this lab was to learn how construct and analyze graphs by figuring out the speed of the buggy car. The question was simple: did the buggy car maintain a constant speed throughout its movement. We will be changing the distance the car has to move and will be recording how long the car takes to move that distance. Therefore, distance is the independent variable while the time would be the dependant variable.
the length of the slope can be used to calculate the speed of the car
4. How would you explain your results using the terms: impulse, momentum, force, and time? Use equations to help you explain the results.
The basic design of a roller coaster consists of a train like coaster that starts out at the bottom of the tallest hill of the ride. The train is then pulled up the hill and is pulled to the top of the hill. As the train is pulled from the bottom of the hill to the top of it, the trains' potential energy is converted onto kinetic energy. Potential energy is defined as "the energy of an object at a height h above some zero level as equal to the work done by the force of gravity"2 (139). Kinetic energy is the energy of "an object . . . because of its motion"2 (132). As the distance between the ground and the train of cars increases, the potential energy of the train increases as well.
Based on the data obtained, Figure 1 represents a force vs. time graph for the amount of force that was used to pull a wooden block across a table. As illustrated in Figure 1, the initial flat line in the graph represents the block at rest, this is where the forces acting on the object are the normal force, gravity, and the static frictional force. Force was then applied to the wooden block until it began to move, the point at which the block moves is the peak in Figure 1. This is the point at which there was enough force applied to the block to overcome the maximum static friction force. The graph then begins to decrease because once a force is applied to the object that is greater than the maximum frictional force, not as much force is needed to continue to pull

The calculus topic I would like to discuss comes from unit two, derivatives. Derivatives are enjoyable because in most cases, they are simple to solve. Also, derivatives make other classes involving calculus and derivatives easier to understand. Within this paper, I will be elaborating on differentiation, the derivative, rate of change, the rules and purpose of derivatives and how to understand them.
Acceleration- is the speed that changes to get you to a constant speed. Acceleration is calculated by (A=Vf-Vi/Tf-Ti). Acceleration equals final velocity minus initial velocity over the final time minus initial time. The cause for the acceleration down the mountain varies by the mass of the person, wind, snow condition, and the type of snowboard that you are riding. Also, hopping once or twice should increase the acceleration time. Acceleration is not only the change of speed, but also occurs when slowing down to come to a stop. This type of acceleration is called negative acceleration.
(b), there is maximum kinetic energy and little potential energy. The kinetic energy propels the train up the second hill
“Even though roller coasters propel you through the air, shoot you through tunnels, and zip you down and around many hills and loops, they are quite safe and can prove to be a great way to get scared, feel that sinking feeling in your stomach, and still come out of it wanting to do it all over again (1).” Thanks to the manipulation of gravitational and centripetal forces humans have created one of the most exhilarating attractions. Even though new roller coasters are created continuously in the hope to create breathtaking and terrifying thrills, the fundamental principles of physics remain the same. A roller coaster consists of connected cars that move on tracks due to gravity and momentum. Believe it or not, an engine is not required for most of the ride. The only power source needed is used to get to the top first hill in order to obtain a powerful launch. Physics plays a huge part in the function of roller coasters. Gravity, potential and kinetic energy, centripetal forces, conservation of energy, friction, and acceleration are some of the concepts included.
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
Upon completion of this task, the students will have photographs of different types of lines, the same lines reproduced on graph paper, the slope of the line, and the equation of the line. They will have at least one page of graphing paper for each line so they can make copies for their entire group and bind them together to use as a resource later in the unit.
