Topics in Work, Energy and Power

1

Scalar Product of Vectors

  • Scalar product (dot product) of two vectors A and B is written as A·B
  • Result is a scalar quantity, not a vector
  • Geometrically represents projection of one vector onto another
2

Work and Work-Energy Theorem

  • Work is done when force causes displacement
  • Work is a scalar quantity that can be positive, negative, or zero
  • No work is done if: displacement is zero, force is zero, or force is perpendicular to displacement
3

Kinetic Energy

  • Kinetic energy is energy possessed by virtue of motion
  • Always positive scalar quantity
  • Depends on mass and square of velocity
4

Potential Energy

  • Potential energy is stored energy due to position or configuration
  • Associated only with conservative forces
  • Can be converted to kinetic energy and vice versa

Key Concepts

The scalar product of two vectorsWork is defined as W =Kinetic energy is the energy possessedThe change in kinetic energyA force is conservative if
