Acceleration

Acceleration, velocity, and gravity are important concepts that each played a role in this lab. Velocity is defined as the speed and direction of motion of a given object. The equation for this particular concept is: v=d/t which states that velocity equals displacement in respect to time. Acceleration is defined as how quickly and in what direction velocity changes. The equation for acceleration is: a=∆v/∆t in which the variable a represents acceleration, ∆v represents the change in velocity,…

Acceleration on ramp: -0.70m/s^2 right Acceleration on flat surface: 0m/s^2 right No they are not similar. As the car rolls down the ramp, it accelerates and when the car is on a flat surface, it continues at a constant velocity (no acceleration). Therefore, it is entirely different as one has acceleration and the other does not. However, if the segment continued until the ball came to a stop, the velocity would slowly decrease and then the acceleration on a flat surface in…

shows the details of the test specimen and the tensile test machine. Figure (4-5):- The specimen and machine test. 4.3. SIMULATION OF SUDDEN ACCELERATION/ DECELERATION OF FUEL TANK A simulation had been designed and manufactured to experimentally predict the behavior of the tank shell with various fuel levels under action of sudden acceleration/deceleration. The simulation idea is subjecting the scaled shell to spring force due to its stretching to some distance then released as…

1. C Why: according to Newton’s first law of motion, an object that is free from all outside forces travels at a constant velocity, covering equal distances in equal times along a straight-line path, C is true. 2. D Why: not matter an object is still or is in motion, the object has inertia all the time. Inertia is a nature/property of any objects. 3. D Why: the ship is moving at a constant speed, which is in a balanced status. For the athlete, it would be likely to do a long jump on ground.…

In the first experiment, the acceleration of a falling mini-basketball, the results gathered disagreed with my predicted outcome. Originally, I could not imagine how the graph might appear. I could not visualize an object falling and what its acceleration, position, and velocity might be on the graph. However, after completing the first experiment, I realized that the graphs would look somewhat the same in relation to the basketball since this object was not affected as much as the lighter…

I think that speed is more important for making a roller coaster exiting. although acceleration is also important for that fast, scary feel in general speed is more important. First of all doing corkscrews or going upside down you need to be going fast so that it is safe. This works by using centrifugal force or inertia. If it is too slow you wouldn’t be able to do it of have to need very heavy buckling for safety and, that wouldn’t be fun. Also I think that the main thrill factor in a ride is…

that as the distance the trolley rolls down decreases, the velocity should decrease with it. Also, because the trolley should uniformly accelerate, the standard equations of motion can be used to calculate many different variables (one such being acceleration using displacement and velocity). This relationship can be confirmed using the SUVAT equation of v2 = u2 + 2as and can be simplified to v2 = 2as as the initial velocity will be a controlled variable set to zero at…

the behavior of a metal block while experiencing uniaxial translation and oscillation in respects to time to calculate the acceleration, spring constant, and damping factor. The experiment was split into two different labs. Part one, the drop test, to take the block to a fixed height and drop it. This would then allow us to calculate the friction force, along with the acceleration of the metal block. Part two, the bounce test, is attaching the metal block to the spring, pushing the block down…

speed. If there is not any friction lost the energy is preserved. Thus, the gravitational potential energy (W) is equivalent to the kinetic energy. This is mathematically expressed as W=KE. With this being said the mass of the roller coaster, the acceleration due to gravity, and the height is equal to 1/2 mv2. The mass is canceled out because mass is being divided on both equations and you are left with the speed of the roller coaster v equal to the square root of 2gh. As a whole, the equation…

ball has a velocity of 1.3 m/s and an acceleration of -9.8 m/s/s. The velocity arrow is now smaller than before and pointing in the positive direction because the racket ball is slowing down in the positive direction at this point in time. The object is at rest during the third point and an acceleration of -9.8. There is not velocity arrow because the object is at rest. When the ball was at the fourth point, the object’s velocity was -1.3 m/s and the acceleration was -9.8 m/s/s. The velocity…
