The speed has nothing to do with the excitement. It is more than likely that most people travel faster on their ride along the highway on the way to the amusement park than they would in a roller coaster. Basically the thrill all comes from the acceleration and the feeling of weightlessness that they produce. Roller coasters thrill people because of their ability to accelerate them downward one moment and upwards the next; leftwards one moment and rightwards the next. How does this thrill machine

The Effect of Gravity on the Human Body According to the NASA Glenn Research Center‚ the nominal acceleration of gravity on Earth at sea level AKA standard gravity AKA “g-force” AKA “1 g” is defined as 32 feet per second. Sneezing subjects your brain to about 3 g and coughing about 3.5 g. The frame of airliners and other transport aircraft must be capable of withstanding a g-force of 2.5 g. A race car driver going around a curve at 100 MPH will experience a g-force of approximately 3

Section A How does the engine size(capacity) of a motor car relate to the acceleration of the car? Hypothesis: The acceleration of a car will increase if the size(capacity) of the engine increases. The car with the biggest engine capacity will take the fastest to reach the velocity of 60km/h from rest position. Method: 1) Arrange to use three different hatchback cars with different engine capacities‚ but

The average driver doesn’t think about what keeps their car moving or what keeps them on the road‚ but that’s because they don’t have to. The average driver doesn’t have to worry about having enough downforce to keep them on the road or if they will reach the adhesive limit of their car’s tires around a turn. These are the things are the car designers‚ professional drivers‚ racing pit crews‚ serious sports car owners‚ and physicist think about. Physics are an important part of every sports and

Motion Problem 1 . A) What is the direction of the acceleration of an object that is slowing down while heading northward? Answer : The acceleration would be southward since the net force required to cause this acceleration would be southward. The change in velocity is directed southward. B) What is the acceleration of an object thrown straight up in the air‚ near the surface of the earth‚ at the very top of its flight? Answer : The acceleration is downwards at 9. 8 m/s 2 .

In order to find this value‚ we will be using a pulley apparatus that will allow us to measure the average velocity and manipulate
