PHY 101: General Physics I (Mechanics)

Learning Outcomes

At the end of the course students should be able to:

  1. identify and deduce the physical quantities and their units;
  2. differentiate between vectors and scalars;
  3. describe and evaluate motion of systems on the basis of the fundamental laws of mechanics;
  4. apply Newton’s laws to describe and solve simple problems of motion;
  5. evaluate work, energy, velocity, momentum, acceleration, and torque of moving or rotating objects;
  6. explain and apply the principles of conservation of energy, linear and angular momentum;
  7. describe the laws governing motion under gravity; and
  • explain motion under gravity and quantitatively determine behaviour of objects moving under gravity.
