Today we are doing a short quiz on Newton's 2nd Law. After the quiz you will have time to finish the mass vs. weight package and activity.
We are finishing the lesson crumple zones and then doing the two activities related to crumple zones.
Today is a work period. You will be completing the Newton's 2nd Law package fully and preparing for an upcoming quiz. We will investigate and learn about crumple zones tomorrow.
Net / Unbalanced Force
When using Newton's 2nd Law we must consider that it is the net / unbalanced force that causes an object to accelerate (speed up / slow down / change direction).
F = ma (Force = mass x acceleration)
Newton's Second Law describes a universal relationship between the external, unbalanced force (F) acting on an object, the acceleration (a) of the object, and the mass (m) of the object.
Newton's 2nd Law - Lesson
From the dynamics package you received in class; go through this guided lesson and then complete the two activities (solve simple questions with the equation and the 20 mark assignment).
Please watch both of these videos to learn more about Newton's 2nd Law.
We are finishing our lesson on Newton's 1st Law today. The kinematics test is tomorrow.
