11/19 class

At the begining of class we took a reassessment on how to find the forces exerted by an object through a free body diagram. After this we had a talk about how we shouldn't just take reassessments over and over. then we went over the motion in two dimensions work sheet that we worked on for homework. an important idea we learned was for a car moving around a curve if the angle between the acceleration and the instanttanious is greater then 90 degrees and is changing direction the car will be slowing down. When the angle is equal to 90 degrees the the car will be moving at a constant speed. when the angle formed is less than 90 degrees the car will have an increasing speed. it is key to remember to the vector of the car's direction is tangent to the curve or circle.
