PHYSICS

Group 2 eto na ung data:



Objectives: (eto ung original pero sabi ni miss dapat daw palitan in your own words.)

1. to be able to determine which measuring device is appropriate for the given item.
2. To be strategic in knowing the data especially with the steel ball.
3. to know how to properly use the vernier caliper.
4. to have the determination in performing the experiment.



Procedure: (dapat drawing/flowchart/diagram)

1. prepare all the materials and then time when the group started.
2. To get the diameter of the ball, place it between two books and then measure the distance between the two books with a ruler. To get the circumference, wrap the sring around the ball and then measure it with a ruler. (Hint: if you are working on a black or dark surface place a sheet of white paper under it.)
3. To get the length of the cube, measure one edge of the face in cm and then in inches using the ruler. Do this in 3 more trials.
4. to get the mass of the metal strip, weight it using a triple beam balance in the grams scale.
5. Record all observations and the time the group finished on the data sheet provided.



Computations: (pinalitan ung data given so palitan niyo na din ung sa %difference natin)

% difference of steel marble:
a. diameter = AV-EV * 100%
AV
= 2.53 - 2.7 * 100%
2.53
= 6.72%
b. circumference = AV-EV * 100%
AV
= 7.948 - 8 * 100%
7.948
= 0.65%


Analysis: Kayo na gumawa.


Conclusion:
Different measuring tools are made for different purposes. It's just the matter of knowing which device is appropriate for a certain object.
