What is the acceleration due to gravity at the space station.
Why do astronauts appear weightless despite being near the Earth?
Basics of gravity and the Law of Universal Gravitation.
An elaboration on how to use Newton's second law when dealing with multiple forces, forces in two dimensions, and diagonal forces.
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.
Newton's second law of motion is F = ma, or force is equal to mass times acceleration. Learn how to use the formula to calculate acceleration.
