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 the motion of systems based on the fundamental laws of mechanics.
4. apply Newton’s laws to describe and solve simple problems of motion;
5. evaluate the 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
8. explain motion under gravity and quantitatively determine behaviour of objects moving
under gravity.
