In this lab, we experimented how the incline of a ramp affects the acceleration of the toy car. In this experiment, we sent a toy car down 3 different ramps at 3 different heights. All 3 of the ramps had the same length of about 3.065 meters to ensure accurate data. We had to record The number of Trials, time, final time, distance, final distance, velocity, final velocity, and acceleration. In our lab the Independent variable was the height of the ramp and the Dependent variable is the Acceleration of the car when going down the ramp. With the small ramp, the average time moving down the ramp was 3.58 seconds. Then the average acceleration for the small ramp was .26 m/ss. That was the slowest time and acceleration out of all 3 slopes. Up second

Rolling a Car down a Ramp Investigation PLANNING When planning my experiment, I will need to take into consideration. the following points: -Fair testing -Equipment -How many results will I get? -What range of variables I will experiment with I will be investigating, by varying the height of the summit of the ramp. is raised off the ground, if the average speed increases or decreases.
When the eggs are dropped onto the pillow, the eggs will bounce a little and stay whole.
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
This experiment was conducted to calculate the running movement and velocity of four people running in a straight line for 100 meters and compare them to the all-star Usain bolt. Usain bolt is the number one all-star ranking, the best and fastest runner ever. The things I could have improved on were that I didn’t really contribute that much to the experiment due to me being sick and non-present for the experiment itself. Things that I did well on were getting down all the results onto the Microsoft excel. The conclusions made from this experiment were that Usain blot is still faster than everyone else and the boys are still faster than the girls by a large amount.
* I will then use a small pile of books and set the ramp up at the
Going into details of the article, I realized that the necessary information needed to evaluate the experimental procedures were not included. However, when conducting an experiment, the independent and dependent variable are to be studied before giving a final conclusion.
In this study, Øverås et al. (2014) experiment’s had two independent variables. The first independ...

The historical results of this experiment by determination of the charge to mass ratio of an electron allowed physicist to work out the miniscule mass of an electron through the use of an external magnetic field. Magnetic fields apply a magnetic force on charged particles perpendicular to their direction of motion and to the magnetic field itself. This allows for the magnetic force to act as a centripetal force which then, through analysis, allows for the determination of certain charged particles through the analysis of their curve radius. In lab 15, Measurement of Charge to Mass Ratio for Electrons, the objective was to measure the charge to mass ratio (e/m) of an electron through the use of a mercury vapor chamber. This was done through the graphical analysis by the linearized equation (4). The goal was to construct a linear graph in which the slope and slope error was calculated using the Linest function, the slope than allows for the derivation of the charge to mass ratio of an electron. Error propagation (error formulas) was also used in this experiment to account for sources of error that could have occurred.
The terms velocity, speed, and acceleration are all very important concepts in physics. They all mean separate things and they have their own conceptual ideas, however they are also very similar. Velocity, speed, and acceleration are all rates of time, but two of them are vectors and one is a scalar, they are all physics concepts, but only one can be positive.
The Relationship between the Angle of Elevation of a Ramp and the Speed of a Ball
One of the first experiment we had in the class was about doors. First, we had to get into groups, preferably 4 people with in it. Secondly, we had to define what a door is. Thirdly, we had to choose a department and examine the doors. Finally, we had to tally up our data and draw a conclusion. My group had a total of three people. We defined a door as an object that blocks off or allows access to somewhere. Being that we were in a sociology class we had to figure out what is the dependent and independent variable. We concluded that the dependent variable was the door while the person in the office was the independent. We examined the foreign language department and the sociology department. From our observations, we saw that the faculty who was a part of the sociology department had more on their door compared to faculty apart of foreign language. When we compared men to women, women had more on their door compared to men. The results of this experiment was predicted.
For my project I choose to show the difference that wearing spikes can make on a runners short sprinting speed. For this experiment I asked for 10 volunteers from the school track and field team to assist me. One-by-one the athletes would sprint (full speed) 50 meters without spikes on and i would record their times. Then after about 5 mins rest they would be asked to put on their spikes and sprint another 50 meters with me recording their times. Then the two times will be compared together for each athlete, to show if running with spikes affects the times that the athletes run. Having 10 athletes run 50 meters (full speed each time) one at a time with tennis shoes on, and record their times for each run (as it is only me timing and in order to get accurate times for each athlete they can only run one at a time.
