What is the acceleration due to gravity at the space station.

Applying Newton's first law to answer some true/false statements about why objects move (or not).

Why do astronauts appear weightless despite being near the Earth?

Figuring out the acceleration of ice down a plane made of ice.

Cellular respiration is the process by which cells derive energy from glucose. The chemical reaction for cellular respiration involves glucose and oxygen as inputs, and produces carbon dioxide, water, and energy (ATP) as outputs. There are three stages to cellular respiration: glycolysis, the Krebs cycle, and the electron transport chain.

Basics of gravity and the Law of Universal Gravitation.

This unit is about how things move along a straight line or, more scientifically, how things move in one dimension. Examples of this would be the movement (motion) of cars along a straight road or of trains along straight railway tracks.

Basic primer on Newton's First Law of motion.

Speed necessary for the space station to stay in orbit.

Viewing g as the value of Earth's gravitational field near the surface rather than the acceleration due to gravity near Earth's surface for an object in freefall.
