When the kinetic energy of a body becomes 4 times its initial value?

So, the momentum is directly proportional to the square root of the kinetic energy. If the kinetic energy of a body becomes 4 times, then the momentum will be the square root of it , and we know that the square root of 4 is 2. Hence, the percentage increase in its momentum is 2 times.

Is the kinetic energy of a body becomes four times of its initial value then new momentum will?

So, p’ the final momentum is twice of initial momentum p. Therefore, the correct option is will be two times of the initial value.

What is kinetic energy when mass is four times?

Hence, The New kinetic energy is 16 times to that of original.

What happens to the linear momentum of an object when its kinetic energy becomes 9 times its initial value?

Thus, the linear momentum of a body is directly proportional to the square root of its kinetic energy. So if the kinetic energy of a body becomes times then the linear momentum of the body will become times. Here the kinetic energy becomes 9 times. Hence the linear momentum will be times.

What happens to kinetic energy when mass of the body is 4 times and velocity is 2 times?

1..if mass doubled then kinetic energy also gets doubled.. 2..if velocity doubled with constant mass then kinetic energy becomes 4 times the initial kinetic energy.. 3..if mass doubled and velocity reduced to half kinetic energy will be half the initial value..

When kinetic energy of a body becomes twice its momentum becomes?

If kinetic energy becomes twice its original value, the momentum becomes √2 times its original value because momentum is directly proportional to the square root of its kinetic energy.

Is the kinetic energy of a body is four times its momentum its velocity is?

Since m is constant , when kinetic energy becomes four times . Velocity become becomes twice of its initial value. Hence new linear momentum becomes twice of the initial value.

What will be the kinetic energy of a body when its mass is made for times and velocity is doubled?

The energy of a body depends on mass and velocity. Kinetic energy is equal to half of the product mass and velocity. SI unit is joules. 1) If mass doubled then kinetic energy also gets doubled.

What will be the momentum if kinetic energy is doubled?

The correct answer is becomes 4 times.

What happened to the kinetic energy of mass is doubled?

Kinetic energy is the energy of mass in motion. When we double the mass, we double the energy; however, when we double the velocity, energy increases by a factor of four.

How can internal forces change kinetic energy?

Moreover, internal forces can never ever change the total mechanical energy (kinetic energy potential energy) of an object. But they can only just convert a part of kinetic energy to potential energy. So they can change the kinetic energy but total energy remains conserved.

Why is momentum twice the initial value of kinetic energy?

If the kinetic energy becomes four times without change in mass, which wont happen unless there is a collision or loose parts dislocated, velocity becomes double. Clearly the momentum becomes twice the initial value….. Momentum (M)=mv and K=1/2m*v^2 and there is a relation between M and K is M=sqrt (2*m*K) so the answer is 2.

What is final momentum 100\% more than initial momentum?

If KE increases to 4 times its initial value , momentum increases to 2 times its initial value. Hence final momentum is 100\% more than the initial momentum. If momentum is increased by 4 times what is its kinetic energy?

What is the SI unit of momentum?

The SI Unit of Momentum is kg.m/s We know that . Substituting for mv in the above equation we get- The above equation gives the relation between Kinetic energy and momentum of the object which is under motion. Hope you have understood the relation between Kinetic energy and momentum of a moving object.

Is the V of a particle the classical momentum of the particle?

No, the v that you are calculating is not the classical momentum of the particle: it is the phase velocity of the wave. The classical momentum of the particle is the group velocity of a wave packet, which turns out to be p/m, but the analysis takes about one week of a QM class.
