Today, we started off class with looking at a constant position vs. time graph. We read the graphs to find the velocity and the acceleration at a certain point. If the line(the object) is moving towards the origin, there is a positive velocity. If the line(the object) starts out positive then becomes zero, there is a negative acceleration. If the slope<0, there is negative acceleration. When there is a constant negative velocity, this indicates that the object has turned around. Also, when trying to find if there is negative or positive displacement in the graph, if the area of the negative slope is bigger than the positive, there is a negative displacement. Afterwards, we put what we had just learned to the test and worked on a worksheet on reading kinematic graphs. On the worksheets, we found acceleration/velocity using position vs. time graphs. If the slope is constant there is a constant acceleration. If there is a positive slope, there is a positive acceleration. And if there is a negative slope, there will be negative acceleration. SLOPE=ACCELERATION. We then used velocity graphs to find the position vs. time and the acceleration of the object.
Tomorrow, we have an assessment on Unit 2:Constant Acceleration.
