Lab: Motion with Constant Acceleration

Question 1

The simulation kept track of the time and automatically recorded data on cart displacement and velocity. If the cart trials were run with a real cart and fan using meter sticks and stopwatches, how might the data compare? Check all that apply.

Revolt · Accepted Answer

There would be variables that would be hard to control, leading to less reliable data.; Meter sticks may lack precision or may be read incorrectly.; Human error in recording or plotting the data could be a factor.

The first part of the graph is a straight diagonal line.; The second part of the graph is a straight horizontal line.; The slope of the first part of the graph is positive, indicating that the cart increased in speed, and was therefore accelerating for the first 4 seconds.; The slope of the second part of the graph is zero, indicating that the cart moved at a constant speed and did not accelerate any more because the fan was turned off.
