Since no one wants to blog, I'll volunteer :)
So in today's class we started our Dynamics Unit.
We got a booklet and were given 4 problems to solve (found on page 5.)
Here are the answers:
1. a) No, the object cannot be in equilibrium because there is a force acting on it causing to accelerate.
b) No, the object cannot be in equilibrium because the sum of the two forces is not zero.
c) Yes, the object can be in equilibrium by having the 2 forces equal and opposite in direction (Fnet=0.)
2)
3)
4)
There was also the other sheet that we went over in class. Here are the answers for
Concept-Development Practice Page 4-1. Chapter 4: Newton's Second Law - Force and Acceleration:
Then we were given a booklet on Chapter 7 Study Guide, finish the first page (Section 7.1: Forces in Two Dimensions) and the other sheet Grade 12 Physics: Dynamics for tomorrow's class.
That's all adios, see you aaall tomorrow :)
Ohh yeaaaah, how can I forget?
