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 I will take
- What range of variables I will experiment with
I will be investigating, by varying the height the summit of the ramp
is raised off the ground, if the average speed increases or decreases.
Method
======
I have decided to produce a step-by-step guide for each experiment
just to ensure that when we actually come to conducting the practical
work, it runs flawlessly. This will also help us conduct fairer tests,
as we will be following the same set of steps each time we collect a
result.
1. Set out equipment as shown in the diagram
2. Ensure the height at the start line (the summit of the ramp) is
10cm using the metre stick
3. Ensure there are no extra weights attached to the trolley
4. Hold the trolley with its front touching the start line
5. Simultaneously start the stop clock and release the trolley (be
careful not to push it or exert any extra force on it)
6. Stop the clock when the front of the trolley reaches the finish
line
7. Record the time taken for the trolley to reach the finish, next to
the relevant height, in a table
8. Repeat from step 4 twice more so you end up with three results for
the same height then continue onto step 9
9. Add all these results together and divide the answer by three to
obtain the average.
10. Record this average in the table
11. By placing more books underneath the raised end of the ramp,
increase the height at the summit by 10cm. Use the metre stick to
check
12. Repeat from step 4 until you have obtained results for height from
10cm through to 25cm

2. A test tube was then filled with 35ml of yeast and placed in the
5. I had to stay after school for an hour in order for Mrs. Logue to elucidate on genetics.
Ever wondered how roller coasters work? It’s not with an engine! Roller coasters rely on a motorized chain and a series of phenomena to keep them going. Phenomena are situations or facts that have been observed and proven to exist. A few types of phenomena that help rollercoasters are gravity, kinetic and potential energy, and inertia. Gravity pulls roller coasters along the track as they’re going downhill. Potential and kinetic energy help rollercoasters to ascend hills and gain enough momentum to descend them and finish the track. Inertia keeps passengers pressed towards the outside of a loop-the-loop and in their seat. Gravity, potential and kinetic energy, and inertia are three types of phenomena that can be observed by watching roller
allow for each subsequent step to take place. And after each step it becomes increasingly
the length of the slope can be used to calculate the speed of the car
5. Add Hcl, as soon as it mixes with the ( ), start the stopwatch
Step 1: EER = 354 – 207.3 + [1.45 X (9.361 X 59.02 + 726 X 1.651)].
* I will then use a small pile of books and set the ramp up at the
He brought in college students, one by one, into a room with six to eight other participants. He showed the room a picture of one line and a separate picture containing three lines labeled 1, 2, and 3. One of the three lines was ...
“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.
Within this set, the investigators randomized how many trials the participants would complete: 7, 10, or 13. Then, they were giving the chance to do 3 or 6 more trials and were ask to record their results.
Before learning the methods from the computer tutorial, I was confused about certain test. B...
Imagine being a paramedic and you just arrived on the scene of a car accident. The car accident involved a man, whose car was driven off the bridge and into a river. The male driver was unable to get out of the car and ended up drowning. On your initial examination of the man’s body, you determined he did not die immediately but attempted to escape the car. Soon his family arrived on site and the man, whom drowned, his wife approaches you, upset and asks you, “If her husband was killed instantly in a crash or did he suffer before he died?” You must decide how you will answer this tough question, rather to lie, defer to someone else, or not to lie to her. Based of Kant’s theories the conclusion is we should not lie to this woman about what happened to her husband but speak the truth to her about the matter.
- The second method I will use is calculating probabilities by the use of conditional probability.
6. I then rinsed out the beaker and glass rod into the flask to make
