Measuring Acceleration
The Speed of Toy Cars & Measuring Acceleration
Introduction:
The Speed of Toy Cars & Measuring Acceleration was investigated by using a ticker timer and changing the angle of the ramp. Changing the angle of the ramp affects the speed and acceleration of the trolley. The speed and acceleration of the trolley was determined by using the ticker timer.
Aim:
The aim of the practical is to investigate the motion and acceleration of a trolley by using a ticker timer and rolling the trolley down a ramp.
Variables:
Independent Variable – The independent variable is the angle of the ramp. The angle of the ramp was changed by adjusting the height of the laboratory jack.
Dependent Variable – The dependent variables are speed and acceleration. …show more content…
The motion of the trolley is a low acceleration on a constant speed. The steeper the slope of the graph, the bigger the acceleration. The slope of this speed-time graph is not steep meaning that the acceleration is low. The gradient of the line is straight, which means that the speed is constant. This is because if the gradient of the line is curved, the acceleration is varied.
The speed of the trolley could have been increased if the angle of the laboratory jack is increased so that the slope of the ramp is steeper. The strengths of this practical, was the ticker tape. The ticker tape visually showed how the motion changed over time. Every five periods between the dots is 0.1 of a second. With the ticker tape we can see the distance and time travelled. The weaknesses of this practical is that the ramp was not accurately measured at a 30° angle. This can vary the results and affect the accurateness, as the slope of the ramp may be different since it was not measured.
The total time it took for the trolley to roll down the ramp is 1.2 seconds. The length of section approximately increased by 10mm for each time interval (0.1 seconds). The average speed of each section gradually decreased towards the end of the slope. The total distance travelled by the toy car is
