Unit 5 Blog Post #2

In class today, we learned about Newton's second and third laws. His second law is "The acceleration of an object is directly proportional to the net force of an object while the acceleration of an object is inversely proportional to an object's mass. Newton's third law is For every force, there is an equal and opposite force. Equal in magnitude opposite in direction. Mr. Blake gave us a good example by poking Gio. When Mr. Blake touched Gio, Gio was also touching Mr. Blake according to Newton's third law. For unit 5, we also reviewed more displacement problems using trig. Mr. Blake showed us force diagrams where we would have to draw the weight and any tensions and etc to solve our problem. We also reviewed more on friction. Friction, or friction force, is a force that opposes motion or impeding motion.

In this picture, Gio is trying his very hardest to go down the slip n slide. Sadly for him, there is friction stopping him from smoothly gliding him down the tarp. We were able to help him out by adding water and soap to give riders smooth glide.
