Is Kinetic Energy Limitless?
does kinetic energy have any upper limit its lower limit would be zero but what about upper limit??

sksaxenaDefinitely it's upper limit is also finite practically. Atleast on earth, force of friction is always an answer to your question, which retards the motion. -
Gautami Shettyokay i get that practically v have a upper limit but what about dis case..
If velocity of anythng is equal to velocity of light (hypothetically) which is the maximum velocity of anythng as far as i know.... Bt if that thng's mass be inc.. Den v dnt knw hw much would the k.e be...???
And if any such thing is made is it possible to stay in earth's surface or would it escape earths gravitational field????? -
Ramani AswathEach celestial object has an escape velocity that is defined by the gravitational field of that object. The escape velocity for earth is a small 11.2 km/sec, way below the speed of light.
Speed Needed to Escape the Earth (Escape Velocity) - The Physics Factbook
You better read some basic physics text on the theory of relativity for your other doubts. Too long to explain here. -
Gautami Shettyi know about escape velocity dats y i said nt practically bt what bout theorotically
-
Ramani AswathYou can calculate the escape velocity for any gravitational system using Newton's Laws. Only black holes prevent any escape. It is unlikely thaat anything within a black hole has a defined mass and shape that can acquire a KE enough to escape.
