Is There Gravity in Space
In a word, "yes" - space is packed with gravity. Hank explains how Isaac Newton described how gravity works, and why even though it seems that things are floating in space, they're still effected by gravity. Every object in the universe...

Position, Velocity and Acceleration
In this video Paul Andersen explains for the position of an object over time can be used to calculate the velocity and acceleration of the object. If a net force acts on a object it will experience an acceleration.

Work and Energy
In this video Paul Andersen explains how the mechanical energy added or removed from a system results from work. For work to occur a force must act parallel to the displacement of the system. Since work and energy are equivalent the...

Matter as a Particle
In this video Paul Andersen explains how matter, like light, can be treated as both a particle and a wave. Louis de Broglie proposed that matter could act as a wave and described the wavelength of matter as a function of Planck's...

Graphing Acceleration Explained - Velocity versus Time!
A velocity vs time graph describes the motion of an object. The slope of the line tells us the acceleration of the object. The slope of the line can be positive, negative or zero. This tells us that the object is either speeding up,...
