Relativity

A well-defined coordinate system which specifies the position and motion of the objects or systems.

• Frame of Reference

• Scalar

• Vector

• Kinetic energy

A frame of reference that obey Newton’s law of inertia and other laws of Newtonian mechanics.

• Non-inertial frame   

• inertial frame

• accelerated frame

• static frame

Who showed that a consequence of the interrelationship between space and time is an interrelationship between mass and energy?

• Isaac Newton

• Galileo Galilei

• James Maxwell

• Albert Einstein

These are used to transform the coordinates of a particle from one inertial frame to another.

• Galilean Transformation

• Newtonian Relativity          

• Einstein’s Relativity

• Maxwell’s law of electromagnetism

A theory that states that the law of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum was independent of the motion of all observers.

• Newton’s Laws of Motion

• Theory of Gravity

• Theory of special relativity

• Theory of relativity

Einstein’s postulate that assumes our inability to detect a state of uniform motion. Many experiments can detect accelerated motion, but none can , according to Einstein, detect the state of uniform motion.

• Postulate of inertia

• Postulate of Acceleration

• Postulate of Constancy

• Postulate of Relativity

A phenomenon of a decrease in length of an object as measured by an observer who is traveling at any non-zero velocity relative to the object.

• Time dilation

• Length contraction

• Relativistic mass increase

• Lorentz transformation

What phenomenon describes that slowing down of time for an object in motion relative to an observer.

• Length contraction

• Time dilation

• Space-time distortion

• Domain expansion

What postulate of the special theory of relativity defines the speed of all electromagnetic radiation is a fundamental law and applies to all inertial frames.

• First Postulate

• Second Postulate

• Third Postulate

• Forth Postulate

What is the formula that describes time dilation in special relativity?

• E = mc²  

• F = ma

• E = ½ mv²

• E = mc
