Chapter2 Sections 2.1, 2.2, Forces Long range and contact. Force measured with a spring scale. Force is a vector quantity. Others vector quantities, position, displacement, acceleration, linear momentum, angular momentum, torque, electric and magnetic fields. Scalars and vectors. Temperature is a scalar, mass is a scalar. scalars are magnitude only) 2.2 Graphical vector addition. The parallelogram that illustrates the sum and difference of two vectors. 2.3 Components of a vector projected on 2D or more D coordinate axes. Vector addition using the components of vectors, 2D case. Sketch the components of a vector in quadrants 1,2,3,4. Adding and subtracting vectors using the components of the vectors. Find the resulting magnitude and direction of n vector (2 < n < ∞) vectors.
