Question

write a lab activity to measure the accleration of an object​

Answer 1

Answer:

The Moving Car

A moving car experiment is a straightforward way of demonstrating that acceleration is a measure of the change of speed of an object using a “photogate.” Photogates use single beams of ultraviolet light to detect a moving object as it passes. They can measure speed to a high degree of accuracy. A toy car can be mounted at the top of a simple flat ramp, such as a length of cardboard or wood. Make sure the ramp is not slippery, or the results will be skewed. The distance from the top to the bottom is measured using a tape measure. The car is rolled down the ramp four times, starting from different points, and timed using a stopwatch. The point at which it passes the finish line can be recorded by the photogate. The results are plotted on a graph to show how the different speeds correspond to an acceleration. Try to measure the time intervals to the nearest 0.0001 seconds and the distances and speeds of the car to the nearest 0.1 cm/s, according to The Science Desk.
