Lab 3: Uniformly Accelerated Motion Your report will consist of the typical 10 parts starting with a testable question. Learning Objectives ● Demonstrate the uniform increase in the instantaneous velocity with time for a cart on an inclined plane and determine the acceleration by using a best-fit trend line to an appropriate graph. ● Determine an experimental value for g (the acceleration due to gravity) by interpretation of the cart’s acceleration as a component of g . 1. Testable Question: How is velocity (v) related to distance (x). 2. Hypothesis: As the distance increase then velocity will also increase because gravity is acting on the car. 3. Variables: Control(s): gravity(g=9.81m/s^2), angle of the track=(5 or 8 degrees), Flag size (s=0.0254m) Independent: Distance (x) m Dependent: Velocity (v) m/s 4. Experimental Design: i Xm sqrt x (m t(ser) V(m/s 1–8 1–8
5. Materials: ● GLX ● Pas Car ● Phone angle measuring ● Photogate ● Ramp 6. Procedure: 1. For this we started with the angle at 5 degrees first and put the car 10 cm away then started increasing the distance by 10 cm each trial until the distance was 80 cm. 2. We then recorded the data that was present on the GLX and transferred that to a graph. 3. After the experiment was done at 5 degrees we then repeated the same thing for 8 degrees. average speed , v = flag ¿ ∆ x time ∈ gate ,∆t ∨ v = ∆ x ∆t o θ = sin − 1 ( ∆ y 122.0 cm ) a = g ∙sin θ = g ∙ ∆ y 122.0 cm .
