Topics in Motion in a Plane

1

1. Scalar and Vector Quantities

  • Scalar quantities have only magnitude and no direction.
  • Scalars follow ordinary algebra for addition, subtraction, multiplication, and division.
  • Examples of scalars include mass, distance, time, speed, volume, density, pressure, work, energy, power, charge, electric current, temperature, potential, specific heat, and frequency.

2. Types of Vectors and Basic Properties

  • Polar vectors have a well-defined starting point.
  • Polar vectors reverse sign when coordinate axes are reversed.
  • Examples of polar vectors include displacement, velocity, radius vector, and force.
3

3. Vector Addition and Subtraction

  • Triangle law states that if two vectors are represented by two sides of a triangle in the same order, the resultant is the third side in the opposite order.
  • Parallelogram law states that if two vectors are represented by adjacent sides of a parallelogram from the same point, the resultant is the diagonal from that point.
  • Vector addition is commutative: A + B = B + A.
4

4. Unit Vector and Resolution of Vectors

  • A unit vector has magnitude 1.
  • The unit vector along A is written as A_hat = A / A.
  • Any vector can be expressed as magnitude times unit vector.
