MEX-009 · Dynamics and conservation laws Sample material

Fundamentals of dynamics. Newton's laws

Dynamics studies the causes of motion — forces. The topic covers the concept of force, Newton's three laws, inertial frames of reference, the main forces in mechanics and an algorithm for solving dynamics problems.
