Today, we read lessons regarding frictional force, normal force and inclined planes from the textbook. There's an assignment on p. 196 numbers 1-4. Ms. K said that the we will a do lab on Tuesday about inclined planes.
We also answered the static equilibrium problems # 3-5.
**If you're given the mass of the object, solve first for the weight. **Draw your triangle with its corresponding angles, then solve for the unknown side which is Ft(tensional force) in this case. Solve it by using trigonometric identies.
