Group-2 Theory of relativity

What is a frame of reference?

• A point where objects collide

• A place where objects can move freely

• An area that can be used to determine speed and position of other objects

• A location where objects disappear

What is an Inertial Frame of Reference?

• A frame where objects move backwards

• A frame where Newton's law holds true

• A frame where objects float in mid-air

• A frame where time stops

What is the speed of light?
