For today's class, we started off by doing the lab or experiment about force and acceleration. As we have learned yesterday from the video by Paul Hewitt about Newton's first law of motion, which states that "when no net external force is acting on an object it will either remain at rest or, if it is moving, it will continue to move in a straight line at constant velocity". We will have to apply what we've learned from recent lessons for this lab.
We started the lab by preparing the equipments needed such as laboratory cart, recording timer, carbon paper discs, pulley, large paper clip, washers, and heavy strings. After that we follow the procedures in the lab handout(if you don't have one, please ask Ms. K for a copy). Make a data table, record your results, sketch a graph for your results and I think we have to answer the Interpretation in the worksheet. Don't worry, Ms. K told us that we still have some class time to finish the lab for tomorrow.
Definition:
Tock - is the distance between two consecutive numbered dots represents one time interval.
Things to remember:
1. Test the sys. to see if you have offset friction. (Hint: put enough washers on big paperclip to offset friction)
2. Label 5 tapes as 50g, 100g, 150g, 200g and 250g. Tapes should measure 1.0 metre long.
3.Data table 7 - 1 needs to be extend(1-16) for tape 1 and 2. This means you need more than 10 entries for 2 tapes.
I think that's all, the one who will scribe for tomorrow's class is Keinaan94.
