Review: Mini-Quiz Percent Error 1) George is adding a rail around his back porch, and he estimates that the length of the porch is 13.5 feet. The actual length is 15 feet. Find the percent error in George’s estimate. Subtract the guess and the actual value to find the amount of error. Answer: The percent error between George’s guess and the actual amount is 10%.

Objective: The student will be able to solve Mathematical Problems related to Physics.

Important Notation To describe vectors we will use: An arrow above the vector: In the pictures, we will always show vectors as arrows Arrows point the direction Magnitude is always positive, the magnitude of a vector is equal to the length of a vector.

Adding Vectors Geometrically (Triangle Method) Draw the first vector with the appropriate length and in the direction specified, with respect to a coordinate system. Draw the next vector with the appropriate length and in the direction specified, with respect to a coordinate system whose origin is the end of vector and parallel to the coordinate system used for : “tip-to-tail”. The resultant is drawn from the origin of to the end of the last vector .
