WebThe kinetic energy of an object is the energy that it possesses due to its motion. The S.I unit of kinetic energy is Joule or 1 kg. m 2. s-2. Mathematically, kinetic energy can be represented as, KE = 1 2 mv 2. Here, m is the mass of the body. v is the velocity of the body. Step2: Examples of kinetic energy are as follows WebSolution Step 1: Given: Initial momentum = m final momentum = 2m Step 2: Formula The kinetic energy is given by the equation E = p 2 2 m where m is the mass and p is the …

WebConservation of momentum. Newton’s second law, in its most general form, says that the rate of a change of a particle’s momentum p is given by the force acting on the particle; i.e., F = d p / dt. If there is no force acting on the particle, then, since d p / dt = 0, p must be constant, or conserved. This observation is merely a restatement ...

Web10 jan. 2024 · Answer: also tripled, factor of 3 Explanation: equation of momentum is p = m * v , where p=momentum, m=mass, and v=velocity if m is unchanged p1 = m1 *v1 p2 = … WebA acceleration is doubled B momentum becomes four times more C kinetic energy is increased to four times D potential energy is increased Medium Solution Verified by Toppr Correct option is C) K.E= 21mv 2 K.E∝v 2 New K.E= 21m(2v) 2=4×K.E ∴ The K.E. of a body will increase to 4 times if its velocity doubles. WebA Its acceleration is doubled B Its momentum is doubled C Its kinetic energy is doubled D Its potential energy is doubled Easy Solution Verified by Toppr Correct option is B) Its momentum gets doubled. momentum is mass times speed p=mv Therefore when speed is doubled, momentum ‘p’ gets doubled. p’=2p Solve any question of Laws of Motion with:- resetear pin
