Question

in this lab, you will learn about finding gravity acceleration using a machine which it is called spark timer for two different masses and then compare its accepted value of g

Answer 1

To find the acceleration due to gravity using a spark timer, measure the distance and time between sparks as an object falls. Calculate the average velocity and then find the acceleration using a formula. Compare the calculated value to the accepted value of gravity.

Step-by-step explanation:

In the experiment to find the acceleration due to gravity, a machine called a spark timer is used. The spark timer creates sparks at equal time intervals as an object falls. By measuring the distance between the sparks and the time it takes for the object to fall, we can calculate the acceleration due to gravity. This value can then be compared to the accepted value of gravity, which is approximately 9.8 m/s² on Earth.

Here is a step-by-step guide on how to find the acceleration due to gravity using a spark timer:

1. Set up the spark timer machine, ensuring that it is securely attached to a stand.
2. Attach a string to a small mass and connect it to the spark timer.
3. Start the spark timer and release the mass. The spark timer will create sparks at regular intervals as the mass falls.
4. Measure the distance between the sparks on the ticker tape. This distance represents the distance the object fell in a given time interval.
5. Measure the time interval between the sparks using a stopwatch.
6. Calculate the average velocity of the object using the formula: average velocity = distance/time.
7. Finally, calculate the acceleration due to gravity using the formula: acceleration due to gravity = 2 * average velocity.

By comparing this calculated value with the accepted value of 9.8 m/s², you can determine the accuracy of the experiment.
