Research Question How an external force, in this case gravity, affects the acceleration of a trolley while on an inclined surface at different angles?
An inclined surface essentially means that the surfaces angle is less than 1800. When the trolley is put on the top of this inclined surface we will measure the time taken by the car to reach the bottom and from that data we will find out the acceleration.
Hypothesis
I think that the trolley’s acceleration will increase due to the fact that the trolley is on an inclined surface. Objects tend to accelerate when going down an inclined surface. This happens because of the unbalanced force acting upon the object. This force is called Gravity, Gravity pulls everything to the center of the Earth, similarly when the inclined surface is tilted this force will act on the trolley and because it moves downwards the acceleration

Place all the materials in the appropriate places.
2. Measure the angle of the inclined surface and ensure the angle is 200.
3. Make sure the blocks are there to support the inclined surface.
4. Have someone place and hold the trolley on the top of the inclined surface.
5. Have the second person to stop the trolley at the end of inclined surface.
6. Have a third person with the stop watch.
7. Let the person with the stopwatch count down.
8. Then after the count down the person releases the trolley.
9. After the trolley’s rear wheels leaves inclined surface stop the stop watch.
10. Record data.
11. Repeat the same experiment with increasing the angle by 50 each time.
Safety
1. Make sure to have a supported incline plane because if not the inclined surface can drop and injure your hand.
2. Make sure a safe distance is kept from the inclined plane as this can injury people.
3. Be prudent when stopping the trolley as car can injure you because of the speed of the
Keeping your upper body and shoulder in place, roll your forearm so your palm faces down on the tabletop. When you can go no farther, use your opposite hand to help roll if farther downward until you feel a gentle to moderate stretch. Hold for __________ seconds. 3 Slowly release the stretch and return to the starting position.
How Mass affects Acceleration down an Incline Sabeena Jagdeo, Brianna O'Donnell, Alec Wigdahl Problem Statement: In this lab some friends are wondering if a roller coaster's acceleration will decrease with less mass in the roller coaster. The purpose is to test whether the mass of the roller coaster impacts its acceleration. Prediction: The roller coasters acceleration will stay constant whether the mass of the roller coaster changes our not. This is true because acceleration is represented by velocity divided by time in equation one.
Start with five or ten repetitions, whichever you feel comfortable with, and gradually build up the number of
Look down the track in both ways to make sure none are coming and then you can cross if there are none. If the lights are flashing you MUST stop. If the lights are not working properly, look both ways and if you can see clearly a mile down each way and there are no trains, you may pass. Do not attempt to drive through, around, or under any crossing gate or barrier, it could
This in turn does not add a greater gravitational pull downward due to the greater level of mass. Which means that the string has added tension, which pulls the cart faster in table number 2. How does the acceleration in Data Table 3 compare with that of Data Table 1? Why do we observe this difference?
“RING!” the school bell went off, which alarmed Konnor and he got up from his seat and dashed out the door and onto the buses. Konnor is the fifth stop on the bus, but the ride only takes around ten minutes. The bus trekked all the way to his house, then he got off and ran inside,
Did you know that there are a lot of different crashes each year about teens on railroads? If you want to stay as safe as possible while crossing the railroad, you must follow all of these rules.. First of all, you should never go on to the tracks if you're not supposed to be there.. Next, you always need to yield to a train. Last of all, you should always stop, look, and listen before crossing railroad tracks.
Early on the morning of October 26, a pedestrian was struck by a train in Ooltewah. Although the man survived, he did suffer a broken arm and lose one of his legs. Accidents like this are preventable when people are willing to take proper precautions around railroad tracks. If you are a pedestrian, consider the following tips when traveling near railroad tracks: Never play or walk on railroad tracks. Trains may come quickly and with little warning.
One other thing I want to cover is if you're a pedestrian with a cross guard down you need to wait even if you don't see a train if the gates are down and the lights are flashing a train is coming even if you don't see it a train is
At one point the van in front of us got stuck in a pile of mud, so we had to sit on this hill with our emergency brake on while the driver of our van helped the other one. Have you ever got stuck on a rollarcoaster in the middle of the most anxious part? The part where you're almost at the top of the upclimb but then boom, you come to a total stop. Think about this situation just like that. Under pressure, I came up with the genius idea of all leaning forward so our body weight wasn't going backward toward the bottom of the hill thinking this might help.
Nevertheless, wheels are capable of shifting directions easily, which in turn adds the difficulty of people’s controlling over it.
Two security guards are called and they wrestle the button from him. The wheel stops at double zero but the protagonist is knocked out by a blow to his
Step 3: After, shell is removed, carefully remove egg from vinegar and place on a paper towel. Step 4: Record observations of the egg after vinegar. (texture, how it looks, etc……) Step 5: Get your triple beam balance and weigh the egg in grams (remember to place a paper towel underneath egg while weighing) Step 6: Record Measurements Step 7: Place an egg in a one of your 2 cups before placing egg name cup distilled water Step 8: Pour distilled water on top to cover the egg Step 9: Place plastic wrap on top of cup to cover the egg filled with distilled water Step 10: Now take your other egg from the vinegar used to take out shell. Step 11: Record observations of the egg after vinegar. (texture, how it looks, etc……) Step 12: Get your triple beam balance and weigh the egg in grams (remember to place a paper towel underneath egg while weighing) Step 13: Record measurements Step 14: Place the second egg in your second cup Step 15: Pour corn syrup on top of the egg to cover
Suppose a conductor is driving his train and the breaks are defect. The rails lead directly into a cluster of five people who would all die if the train will go this direction. However, the conductor can change onto another track where only one person is standing hence only one person would die. How should the conductor react (Hare, 1964)? Is it possible to condense the problem to a rather simple maximization problem in example that the action is taken, which would kill the least people?
