This short YouTube video introduces you to the planets which make up the solar system.
This online article delves into our the sun and planets were formed.
An exploration of how the area under a force vs. position graph equals the work done by the force and solves some sample problems.
An exploration through some example problems on the concept of work.
Speed necessary for the space station to stay in orbit.
What is the acceleration due to gravity at the space station.
Why do astronauts appear weightless despite being near the Earth?
What would fall faster on the moon, a brick or a feather?
Figuring out the acceleration of ice down a plane made of ice.
Explore the various forces acting on a block sitting on an inclined plane. Learn how to break the force of gravity into two components - one perpendicular to the ramp and one parallel to the ramp. Finally, using geometry and trigonometry, learn how to calculate the magnitude of each component of force that is acting on the block.
