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). My audio on my computer doesn't work with windows 10 so I had to just take a picture of the note...sorry. I made a video, but it had no sound.
Please watch both of these videos to learn more about Newton's 2nd Law
