What is the inspiration for our exploration?:
Sir Isaac Newton’s law of motion: An object will remain at rest or in uniform motion in a straight line, unless acted upon by an external unbalanced force.
The law (above) lead to Newton’s second law, which is what we are experimenting with: Force= mass X acceleration, F=ma
The force= unbalanced force. Expressed as 1N, or one Newton.
What does the experiment entail?:
The experiment was set up to test the amount of weight we put on a pulley system, and how much power(total amount of work done, the amount it took) it took to work (force times parallel distance. was required for it to move) . We placed weights of 20, 10 and 5 grams on a pulley hook, and first tried to fool around with different speeds, just to get on a more comfortable level with different speeds and weights.
We established a constant weight of 190g, or .19kg to test the first round of our pulley system. It works, and we are able to move on to building a series of 4 graphs, our group only put together 2.
Hana! i love your post, the pictures are great and help the reader to understand exactly how the experiment worked. great job!
