Motion with Constant Acceleration Lab Report

Introduction In this lab , I used a simulation to measure the position and velocity of a cart as it accelerated along a gentle surface. This lab was a virtual lab, in which I calculated the average velocity of the cart, and used velocity vs. time graphs to determine the acceleration of the cart.

Purpose: To observe how an object's position and velocity change while moving at a constant acceleration.

Question: How does an object's position and velocity change as it accelerates? Hypothesis: If there is a greater fan speed, there will be greater acceleration because greater fan speed gives more power to move the cart. Independent Variable: Fan speed

Dependent Variable: acceleration of cart Materials I used ●

Computer

Procedure Step 1: Open the fan simulation. Step 2: Put fan speed on low to identify any changes in position, velocity, and acceleration in the cart. Step 3: Put fan speed on medium to identify any changes in position, velocity, and acceleration in the cart. Step 4: Put fan speed on high to identify any changes in position, velocity, and acceleration in the cart. Step 5: Calculate the data and put it in a table.

Observations of Position vs Time Graphs

The line is curved. The positions of the cart are further apart because the velocity increased. Similar to low speed fan graphs but the slope is steeper. It can move further each second.

High

Slope is even more steeper than the medium fan speed graph. The cart moves the farest each second because the speed is the greatest; so it takes less time to cover distance.

Conclusion In conclusion, the experiment helped me know how acceleration and speed affects the movement of an object. I used the total distance traveled by the cart and divided it by the elapsed time for each cart, to determine the average velocity for each cart. Overall, my hypothesis was correct and my data supports my hypothesis as well....
