⚙️ Classical Mechanics — Intro#

Scope — Motion of objects under forces, using Newton’s laws as the foundational framework.

Key concepts#

• Kinematics — description of motion (position, velocity, acceleration) without regard to cause.
• Dynamics — relationship between motion and the forces producing it.
• Newton’s laws — three principles governing inertia, force–acceleration, and action–reaction.

Seed Q&A triads#

• Q: What does classical mechanics describe?
  A: The motion of macroscopic objects at speeds much less than the speed of light, where quantum effects are negligible.

• Q: What is inertia?
  A: The tendency of an object to resist changes in its state of motion unless acted on by a net external force.

• Q: How are velocity and acceleration different?
  A: Velocity describes how fast position changes; acceleration describes how fast velocity changes.

Quick activities#

• Sketch position–time and velocity–time graphs for an object moving at constant acceleration.
