Introduction to mechanics

Mechanics is the science of the mechanical motion of bodies and their interactions. The topic covers the branches of mechanics, physical models, frames of reference and the relativity of motion.

Estimated time: 2 h 50 min 3 activities

Learning objective

Explain the subject, aim and branches of mechanics.
Learn the conditions under which the point-particle, rigid-body and continuum models apply.
Master the concept of a frame of reference and the relativity of motion.
Learn to apply Galileo's velocity addition rule in problem solving.

Expected outcomes

Distinguishes what kinematics, dynamics and statics study.
Can justify whether a body may be treated as a point particle in a given problem.
Explains why the trajectory and velocity differ in different frames of reference.
Solves relative-motion problems: river crossing, escalators, trains.
