1 Kinematics
Kinematics describes motion without its causes. For constant acceleration: v = u + at, s = ut + ½at², v² = u² + 2as. Velocity is the rate of change of position; acceleration is the rate of change of velocity.
Classical Mechanics Beginner
Motion, Newton's laws, energy and momentum — the foundation of engineering dynamics.
📚 Lessons
2 Newton's laws
1st: a body stays at rest or constant velocity unless acted on by a net force. 2nd: F = ma — force equals mass times acceleration. 3rd: every action has an equal and opposite reaction. These three laws underpin statics and dynamics in engineering.
3 Energy & work
Work W = F·d transfers energy. Kinetic energy KE = ½mv²; gravitational potential energy PE = mgh. Energy is conserved: in a closed system total energy stays constant, converting between forms.
4 Momentum
Momentum p = mv is conserved in collisions. Impulse F·Δt = Δp explains why crumple zones and airbags reduce injury — by extending collision time they lower the peak force.
