Why do astronauts appear weightless despite being near the Earth?

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.

Outcomes:

• Determine if a liquid is acidic, basic, or neutral
• Place acids or bases in relative order
• Describe on a molecular scale, with illustrations, how the water equilibrium varies with pH
• Determine concentration of hydroxide, hydronium and water at a given pH
• Relate liquid color to pH
• Predict (qualitatively and quantitatively) how dilution and volume will affect the pH and concentration of hydroxide, hydronium and water

Speed necessary for the space station to stay in orbit.

Use two methods to find the sum of mixed numbers: improper fractions and mixed numbers

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.
