What will happen to momentun if kinetic energy is tripled?

Answer 1

It depends on the mass of the object.K.E = 1/2mv2 =1/2mv*v = 1/2pv where p = momentum = mass * velocity.That is K.E = 1/2 pv.momentum depends on mass and velocity.Let in the first case K.E =1/2pv....(1) in the second case K.E = 1/2p1v but p1 = 3p. Then K.E = 1/2*3pv = 3*1/2pv = 3*K.E.

Answer 2

Kinetic energy K is defined as K = 1/2 mv^2, where m is the mass of the particle and v is its speed. Momentum p is p = mv. Simple algebra will show that kinetic energy can be written in terms of momentum as K = p^2 /2m.

If the kinetic energy of a particle is tripled, then its momentum must increase by the square root of 3, or about a factor of 1.732.

Answer 3

If kinetic energy is tripled, momentum will remain the same. Momentum depends on the mass and velocity of an object, whereas kinetic energy depends on mass and velocity squared. Since velocity is squared in the kinetic energy formula, tripling the kinetic energy will only change the velocity by a factor of the square root of 3, which will not affect the momentum.
