What you will learn
Course Introduction
Start here!
Skating
Professor Bloomfield examines the principle of inertia through skate boarding. Objects at rest tend to remain at rest while objects in motion, tend to remain in motion. Why does a stationary skater remain stationary? Why does a moving skater tend to continue moving? How can we describe the fluid, effortless motion of a coasting skater? How does a skater start, stop, or turn? Why does a skater need ice or wheels in order to skate? Physics concepts covered include Newton’s first and second laws and 5 physical quantities: position, velocity, acceleration, force, and mass.
Falling Balls
Professor Bloomfield examines the physics concepts of gravity, weight, constant acceleration, and projectile motion working with falling balls.
Ramps
Professor Bloomfield examines the physics concepts of Newton’s third law including conserved quantities, support forces, work, energy, and mechanical advantage working with ramps.
