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
6. explain and apply the principles of conservation of energy, linear and angular momentum;
describe the laws governing motion under gravity; and
7. explain motion under gravity and quantitatively determine behaviour of objects moving under
