Acceleration of a Trolley

The accelerated unbalanced force in the car plan can accelerate the object. Acceleration occurs in the same direction as the resultant force (or unbalance). The size depends on the mass of the object and the magnitude of the force. The force exerted on a small object is larger than the force acting on a large object. The acceleration is increased as the mass is the same and the power rises. The formula for obtaining the acceleration is as follows. [IMAGE] = initial speed, [IMAGE] = variable acceleration of the trolley along the tilt Acceleration is: T [IMAGE] = [acceleration], [IMAGE] = last speed,

The variables that remain unchanged for fair testing are the type and distance of the cart. The variables to be changed are the acceleration of the trolley, the mass on the trolley, the surface of the slope and the height of the slope. The argument that I change will be the quality of the trolley. The measurable dependent variable is the acceleration of the trolley through the shutter. The result I removed from the elastic material was inaccurate as follows: 1 / mass (kg) Acceleration (m / si) at the mass (kg) of the dolly

Set up a device for measuring acceleration. First set the height to 15 cm and the length of the slope to 227 cm. At this height there is a possibility of slipping by gravity, so there is no need to add power to the car to accelerate the car. In this way, you can keep gravity constant. Next, measure the acceleration using the ticker and the ticker. I drop the ticker on an 850 gram trolley. Since 0.2 seconds is displayed for every ten marks on the ticker tape, cut the ticker tape with 10 marked strips. By drawing a strip on the chart you can see how fast the car is moving. From now you can calculate the acceleration of the car.

I calculate the acceleration using a ticker because it shows the speed at which the acceleration changes. Calculating the time it takes a cart to reach the end of the cart only gives the average acceleration. We can not measure changes in acceleration. Since the results of the first test are too close to each other, we added 400 grams of quality every time so that correlations can be seen when adding 100 g each time. Therefore we decided to add weights to make the results clearer and to see if quality affects acceleration. In this way the results are more different and the correlation becomes clearer.
