Trolley Investigation

Before starting the survey of the selection investigation of the car survey, it is necessary first to decide which variable to investigate. Variables can be categorized into two broad categories: dependent variables and independent variables. When measuring the movement of the trolley, the dependent variable is the speed. The speed changes as other variables change. Independent variables are variables that are not affected by other variables. There are many independent variables in measuring the behavior of a trolley, and I must first evaluate which is the right thing to study: * Trolley shape - Trolley shape and Aerodynamics

Purpose - The purpose of this survey is to find out how certain variables affect the cart's final speed. I use rising lamps and trolleys to investigate it. Examine the relationship between the height of the slope (rolling the truck) and the final speed when the truck leaves the slope. Hypothesis - I predict that the final speed of the car will increase as the height of the lamp increases. It can also be easily measured. When gravity pulls the car toward the earth, the car accelerates along the ramp. As the ramp goes up, the trolley will be higher

A survey is to investigate how the height of the runway affects the average speed of the cart. In order for the survey to be a fair test all other factors or variables should remain unchanged. The investigation must be carried out in a fair way, otherwise the result will be incorrect and the conclusion will be inaccurate. A variable that may affect the speed of the cart is that the experiment may be affected by the height of the lamp. The higher the lamp, the faster the car moves. Because it stores more gravity energy when the car is on the ground. Since the increase in speed is proportional to the increase in gravitational energy, the speed continues to rise.

The prediction of this survey will be higher quality, faster, more powerful, faster. METHOD: The method of this survey: first roll the trolley to the slope to ensure that the height of the slope does not change. Since gravitational potential energy (G.P.E) is applied to undesirable results, it is difficult to obtain an accurate measurement of acceleration using this method. G. P. E = massi ?? heighti? In the gravity method, use two elastic members to push the trolley forward
