Newtonian Dynamics
Newton's Laws of Motion
Understand the three fundamental laws: inertia, the relationship between force and acceleration (F=ma), and action-reaction pairs.
Force Analysis and FBDs
Learn to use Free-Body Diagrams to isolate objects and resolve various forces like gravity, tension, and normal force.
Friction and Circular Motion
Explore the mechanics of static and kinetic friction, as well as the centripetal forces required for curved paths.
Work and Energy
Work and Kinetic Energy
Understand the mathematical definition of work, the relationship between force and displacement, and the Work-Energy Theorem.
Potential Energy Types
Explore gravitational and elastic potential energy and how energy is stored based on an object's position or configuration.
Energy Conservation Laws
Master the distinction between conservative and non-conservative forces and apply the principle of conservation of mechanical energy.
Momentum and Collisions
Linear Momentum and Impulse
Learn the relationship between mass, velocity, and the change in momentum caused by time-varying forces (Impulse).
Conservation of Momentum
Understand how momentum is conserved in isolated systems and how to analyze different types of collisions (elastic vs. inelastic).
Center of Mass Dynamics
Explore how to locate the center of mass in a system and how external forces dictate its collective motion.
Rotational Mechanics
Rotational Kinematics and Torque
Moment of Inertia
Understand how mass distribution relative to an axis affects an object's resistance to rotational acceleration.
