Hypothesis: As slope increases, acceleration increases. Introduction: Speed is the distance traveled per unit time, velocity at any given moment is the slope of the tangent line through any relevant point on the graph, acceleration is the rate at which an object changes its velocity, and instantaneous acceleration is acceleration at any particular instant of time or the limiting value ∆ v/∆ t as the time interval (∆ t) gets vanishingly small. Speed Formula Velocity Formula Acceleration Formula (also Instantaneous) Ave. speed = distance Ave. velocity = ∆ position = displacement Ave. a = ∆ velocity = vf-vi time time time time time (Ex.

Analysis: One source of error comes from the slight time delay in human reaction initiation when using a stopwatch to time the car as it rolls down the ramp. This can have a small effect on calculations, so someone more alert should operate the stopwatch.
The Essay on Versus Time Acceleration Cart Prediction
Physics Lab Report Statement of the Problem: The problem that was arisen in Problem #5: Motion up an Incline was in reference to a change in acceleration in both an uphill and downhill motion. The question on hand was whether or not the acceleration was the same going uphill as it was downhill or different from each other in both directions. To obtain a secure conclusion this experiment required ...
Another error can occur when the photo gate gives the wrong calculations. This can happen if a sufficient area of the card on top of the car doesn’t pass through the photo gate. Angle and position the photo gate so enough area of the card passes through it.
