Explanation:
You are probably familiar with the word speed. In the examples given above, a higher speed seems to indicate that a given distance has been covered in a shorter time, or a larger distance covered in a given time. The most convenient way to find out which of the two or more objects is moving faster is to compare the distances moved by them in a unit time. Thus, if we know the distance covered by two buses in one hour, we can tell which one is faster. We call the distance covered by an object in a unit time as the speed of the object.
Step 1: Place the constant velocity car in position on a surface, with plenty of space in front of it. Use the duct tape to mark the starting position of the car, placing a piece right behind the back wheels.
Step 2: Measure a distance from the tape, a few meters along the floor (longer is better), and place a second piece of duct tape. Note down the total distance.
Step 3: Turn on the motorized car, place it in position in front of the starting tape, and release it, starting the stopwatch at the same time.
Step 4: Stop the stopwatch when it reaches the second piece of tape, and note down the time in a data table that looks something like this:

Step 5: Repeat the experiment at least five times, and note down all the trials.
Step 6: Find the average of your five or more trials by adding up the numbers and dividing by how many trials you did.
Step 7: Calculate the speed of your car using the equation: speed equals distance divided by time.
