19-11-14 Getting ready for forces quiz
Today’s assignment from textbook:
p. 110-112: 20, 37, 38, 39, 41 and 51.
What you need to know for tomorrow’s quiz:
- Use of first five equations in your equation sheet
- Draw force diagrams
- Evaluate forces to determine balanced/unbalanced net force
- Special circumstances/types of problems
- Solve problems with pulleys (pulleys change direction of tension, not magnitude)
- Solve problems with ramps
- Solve problems with forces at angles
- Break down forces into x and y components
- Solve triangle math using SOHCAHTOA and law of sines
