Curated OER
Newtonian Mechanics
Students familiarize themselves, through teacher demonstration, with Gavendish's apparatus first used for experimentally determining the value of the Universal Gravitational Constant G, and calculate theoretical value of Earth's...
Curated OER
Momentum
Students learn the concepts of momentum and its conservation, using the recoil of a cannon as an example. They examine how momentum is a vector, allowing its conservation to be applied to problems in 2 and 3 dimensions.
Curated OER
Bounce (Projectile Motion And Collisions)
Pupils analyze the motion of an object as it moves through a complex path that includes rolling, falling, and bouncing. They answer questions related to what forces are acting at any given time.
Curated OER
The Celestial Sphere
Students are introduced to the celestial sphere, describing its apparent rotation and the special role of the pole star.
Curated OER
Newton's 3rd Law
Students examine how the formal definition of Newton's 3rd law: forces always originate in pairs, equal in magnitude and opposite in direction. They also examine how the informal, qualitative version: Each action has an equal and...
Curated OER
Motion in a Circle
Students explore uniform circular motion, and the relation of its frequency of N revolutions/sec with the peripheral velocity v and with the rotation period T. They examine how uniform circular motion is a type of accelerated motion.
Curated OER
Frames of Reference: The Basics
Students learn the concept of frames of reference in physics. They examine how two frames of reference, each moving with respect to the other with a constant velocity v (constant speed, constant direction).
Curated OER
Seasons of the Year
High schoolers examine how the link between the tilt of the Earth's axis to the ecliptic and seasons of the year--length of day, effectiveness of sunlight, polar day and night, and seasons south and north of the equator, as well as near it.
Curated OER
Airplane flight
Students learn the basic concepts about airplane flight. They learn the reason jetliner wings are swept back and why jet engines have replaced propellers in high-speed flight.
