Photogates Lab Report

     As you’re driving on your way to work one morning you notice a brand new bright red Corvette approaching fast in your rear view mirror. The speed

The track begins with a steep climp, building up potential energy in the coaster car. The rest of the

The purpose of this lab was to test the relationship between velocity, position and time. As well as identify how accelerations affects an object's velocity and time. In this experiment, we will collect data on velocity, speed, and time. We used the equation Y=mx+b, in order to compare the velocity of each trial by comparing the slope and the y-intercept. If the slope was steeper on the graph, this meant that the cart had an increase in velocity. If the cart maintains at a constant speed, then the cart will have an increase in acceleration. In class we learned about the principles of acceleration, time, and velocity. Acceleration is an object’s increase in velocity. Velocity is how

Next, the independent variable was the sail car and shed car. The speed acceleration was the dependent variable. The constants marble distance of photogate the angel of the track.

The whole trip, the speed limit was 70 miles per hour. Bob is used to the speed and forgot the speed limit decreases to 35 miles per hour. When Bob and Tammy entered Miami city limits Tammy noticed a patrol car behind them. The patrol car followed them for about a minute before she saw the red and blue lights come on. Bob noticed the patrol car also and pulled into a Dairy Queen parking lot. Bob’s behavior changed in an instant. Bob starts to sweat, and he is gripping the steering wheel.

A car in a roller coaster moves along a track that consists of a sequence of ups and downs. Let the x

We were given groups to design and make a mousetrap powered car that will roll as far as possible. This will be measured and be put into a graph. We will make three modifications to our mousetrap car over the course of the experiment. We have a variety of different materials, including plastic, wooden wheels and a dowel, screws, mousetrap, blue tack and a piece of string. Forces were acting in a negative way and a positive way on the car. Gravity was pulling the car down to the ground. Uplift was pushing up upon the car against gravity. Drag was also known as friction, holding back the car while it was moving. Thrust was in the cars favour, pushing forward against the force drag. There were also many forms of energy being used and being wasted like heat and sound energy. Potential energy was stored in the mousetrap, propelling itself forward. Kinetic energy was also demonstrated when the car started to roll.

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.

When the mousetrap car moves down the track, the speed of the mousetrap car decreases, therefore my hypothesis was supported. At 1 second, the mousetrap car was traveling at a speed of 3.2 m/s. At 2 seconds, the mousetrap car was traveling at a speed of 2.35 m/s. At 3 seconds, the mousetrap car was traveling at a speed of 1.53 m/s. At 4 seconds, the mousetrap car was moving at a speed of 1.2 m/s. At 5 seconds, the mousetrap car was traveling at a speed of .98m/s. “A car will eventually come to a stop if just allowed to roll as the friction between the road surface and the wheels causes friction that causes the vehicle to stop,”(Examples of Rolling Friction). The evidence supports the claim because the wheels of the mousetrap car are moving

The aim of the experiment is to examine how the acceleration of the car differs when the angle of inclination of the ramp is amplified and to record and analyse findings.

This occurs when an object falls and is not inhibited by other objects2 (314-315). As the train goes down the hill, the coasters’ mass causes it to accelerate faster than the people in the car. During the free fall stages of the ride the train does not exert any pressure on the riders or the track causing the riders to feel momentarily

Photosynthesis is essential to all living organism such as animals and plants. Photosynthesis is a process used by plants and other autotrophs to capture light energy and use it to power chemical reaction that converts carbon dioxide and water into oxygen, carbohydrates and water. (Textbook: Principles of Biology). The reactants and the products of photosynthesis are:

How does the incline of the ramp effect the time it takes for a car to go down a ramp?

For my speed test, I rolled a marble down a “ramp”. First, I measured 2.5 meters on a measuring tape, then, using a calculator, I split 2.5 meters into 5 equal distances (0.5 meters), which I marked using sticky notes so I would know where to press the “lap” button. Then, I noticed that the measuring tape was curved in, which could keep the marble on the “ramp”, so I had an idea that instead of rolling the marble on the floor, I could roll it on the measuring tape. I used tape to fix some of the lopsided parts on the measuring tape. Then, I started testing my marble’s speed. I rolled my marble down the track with a gentle push, and pressed “lap” at each lap marking (using the stopwatch on my computer). Then, after I got my split times for the

A rightward moving rider gradually becomes an upward moving rider, then a leftward moving rider, then a downward moving rider, before finally becoming a rightward-moving rider once again. There is a continuing change in the direction of the rider as he/she will moves through the clothoid loop. A change in direction is one thing of an accelerating object. The rider also changes speed. As the rider begins to climb upward the loop, he/she begins to slow down. What we talked about suggests that an increase in height results in a decrease in kinetic energy and speed and a decrease in height results in an increase in kinetic energy and speed. So the rider experiences the greatest speeds at the bottom of the loop. The change in speed as the rider moves through the loop is the second part of acceleration which the riders experiences. A rider who moves through a circular loop with a constant speed, the acceleration is centripetal and towards the center of the circle. In this case of a rider moving through a noncircular loop at non-constant speed, the acceleration of the rider has two components. There is a component which is directed towards the center of the circle (ac) and relates itself to the direction change and the other component is directed tangent (at) to the track and relates itself to the car's change in speed. This tangential component would be
