• The "m" in E = mc^2 is the rest mass of the object. Further more, E = mc^2 is not the complete equation, the object's momentum component is often omitted. Although photons have no rest mass, they do have momentum since they have energy (P…

• False. Velocity is a vector, and as such is has a magnitude and direction component. The speed of the car may remain constant, but if the direction of the car is constantly changing (turning on the ramp), then the velocity is NOT constant. Wh…
