Motion: The Acceleration of a Cart on an Incline Purpose: To use the provided information of positions and times of a cart rolling down an incline to calculate the acceleration of the cart. Procedure: In the video there was a motion sensor that was going to track the cart as it rolls down the incline. There was another motion sensor that was connected to a wireless interface that is going to send the data from the cart going down the incline to the computer. The motion sensor records the positions and times and the interface sends them to the computer. The upper and lower graphs were displayed. The upper graph shows the position and time which was used to give us our information for the cart. The lower graph shows the speed and the time of the cart. It showed how the cart is steady in the beginning and then it takes off and then crash. There was a tool used to show the positions every 0.500s. These two graphs gave us our data for the cart. Data and Results: Motion: Data and Results Position, cm Time, s Distance (d), cm Change in time (Δt), s Average Speed (v), cm/s Change in Speed (Δv), cm/s Acceleration (a), cm/s 2 19.7 0.950 5.8 0.500 11.6 25.5 1.450 19 38 15.3 0.500 30.6 40.8 1.950 18.4 36.8 24.5 0.500 49 65.3 2.450 18 36 33.5 0.500 67 98.8 2.950 17 34.8 42.2 0.500 84.4 141.0 3.450 Avg accl. 6.4 Calculations: 1

Discussion: As the cart rolls down the incline the distance the cart traveled every half second is increasing. The cart is accelerating so the distance covered in each half second interval will be greater than the last one. The cart is accelerating so its speed is getting faster with each moment that passes. When a cart rolls down the incline the acceleration will stay constant if there is no external force acting on it. This comes from Newton’s Law of Inertia, which states that an object will continue to move at a constant velocity unless acted upon by an external force. Destinee Santiago (2023) 3
