decribe an experiment you could perform to determine the average speed of a toy car rolling down an incline
average speed= total distance/time.
To determine the average speed of a toy car rolling down an incline, you can perform the following experiment:
1. Set up an inclined plane by propping up one end of a smooth, sturdy surface (such as a wooden board) with books or a stand. Make sure the incline is at a constant angle throughout.
2. Measure the height of the inclined plane (the vertical distance from the starting point to the end point of the car's path).
3. Mark a starting point at the top of the incline and an ending point at the bottom.
4. Place the toy car at the starting point, ensuring it is at rest and not in motion.
5. Use a stopwatch or a mobile phone with a timer to accurately measure the time it takes for the toy car to roll down to the ending point.
6. Repeat the experiment multiple times to obtain more data points and increase the accuracy of your measurements.
7. Calculate the average speed of the toy car by dividing the total distance traveled (length of the incline) by the total time taken (the average of the time recorded in each trial).
Average Speed (m/s) = Distance (meters) / Time (seconds)
By performing this experiment and calculating the average speed of the toy car, you can determine how quickly it rolls down the incline.
