You can vary the values of initial position, initital velocity and acceleration. Three digital clocks indicate the time elapsed since the start. As soon as the car has reached the green respectively red light barrier with its front bumper, the corresponding clock will stop.

Young 2,913 solutions Pre-Lab Information PurposeExperimentally observe how an object’s position and velocity change while it is moving with a constant acceleration. TimeApproximately 50 minutes QuestionHow does an object’s position and velocity change as the object accelerates? Hypothesis If the fan speed increases, then the acceleration of the cart increases, because a greater fan speed supplies more energy to move the cart. VariablesIndependent Variable: fan speed Dependent Variable: acceleration of the cart Constant: mass SummaryYou will use a simulation to measure the position and velocity of a cart as it accelerates along a frictionless surface. Complete three trials using three different fan speeds to move the cart and generate data, and then calculate the average velocity of the cart for each of the three fan speeds. You will also determine the acceleration of the cart from a graph of Velocity vs. Time. Finally, run one more trial in which the acceleration will be removed halfway through the run to interpret how velocity changes. Please note that this simulation uses the term “speed” instead of “velocity.” This is because the cart moves only in one direction. For the purposes of this lab, the terms speed and velocity are interchangeable. Lab Procedure Step 1:Open the simulation. a)Be sure to follow all the directions provided in the lab guide as well as on screen during the virtual lab. b)Open the Gizmo “Force and Fan Carts” link in the virtual lab and watch the demo by clicking the demo icon at the bottom-left corner of the activity. c)When the demo is complete, close it and return to the Experiment setup. Virtual Lab: Motion with Constant Acceleration What is the purpose of the constant acceleration lab?The purpose of this lab is to investigate uniformly accelerated motion by using a dynamics track and cart with a "Smart Timer" ticker tape system.
What do you mean by constant acceleration 9th class?Constant acceleration is defined as a change in velocity that does not vary over time. If a car increases its velocity by 20 mph in one minute, then another 20 mph the next, its average acceleration remains constant at 20 mph per minute.
How do you find constant acceleration?The equation v – = v 0 + v 2 v – = v 0 + v 2 reflects the fact that when acceleration is constant, v – v – is just the simple average of the initial and final velocities. Figure 3.18 illustrates this concept graphically. In part (a) of the figure, acceleration is constant, with velocity increasing at a constant rate.
How do you calculate acceleration in a lab?Introduction: Acceleration is the rate of change in velocity (speed and direction). It is calculated by subtracting the initial velocity from the final velocity and dividing this by the time it took for the change. In this lab we are going to equate speed and velocity.
