Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum.

When velocity is doubled Which of the following is doubled?

Detailed Solution. The correct answer is Momentum is double. If the velocity is doubled its kinetic energy is multiplied by four times. So, if the velocity is doubled, momentum also doubles.

What does doubling an object’s velocity do to its momentum and to its kinetic energy?

In fact momentum is mass multiplied by velocity. Kinetic energy of a body of given mass, is directly proportiional to its square of its velocity. When momentum is doubled, mass remaining constant, this means velcity is doubled. Hence, kinetic energy becomes 22=4 times i.e. say from 100 units to 400 units.

What happens to an object’s momentum if its velocity is halved?

No change in momentum.

When momentum Open object is doubled in magnitude what happens to its kinetic energy?

Kinetic energy is directly proportional to the squared of the velocity. This means that when momentum is doubled, mass remaining constant, velocity is doubled, as a result now kinetic energy becomes four times greater than the original value.

When the velocity of an Aeroplane is doubled the momentum Mcq?

Answer: (a) when the velocity of the aeroplane is doubled, its momentum also gets doubled. However, the combined momentum of aeroplane + air is conserved. As the momentum of the aeroplane increases, the momentum of air also increases by an equal amount in the opposite direction.

When distance is fixed if velocity is doubled then time become?

Therefore, when velocity is doubled, the time becomes 1/2.

What would happen to an object’s momentum if its mass is halved and velocity is doubled?

Let the initial momentum be ‘mv’. But given that, velocity is doubled and mass is halved. Hence the momentum of the body would remains the same.

What happens to an object’s kinetic energy when its mass is doubled and speed is half?

We know that kinetic energy is equal to half times product of mass and velocity: K.E.=1/2(mv^2). This implies that kinetic energy gets doubled.

What is the relationship between velocity and momentum?

In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. where m is the mass and v is the velocity. The equation illustrates that momentum is directly proportional to an object’s mass and directly proportional to the object’s velocity.

When velocity of a body is doubled its linear momentum becomes twice True or false?

If the velocity is doubled its kinetic energy is multiplied by four times. And there is no relationship between the velocity and potential energy. So, if the velocity is doubled, momentum also doubles.

When the mass and velocity are doubled the kinetic energy will?

Hence, if mass and velocity will get double then the original kinetic energy will become eight times of itself.

How does momentum change when mass is doubled?

The momentum of an object is calculated as the product of mass and velocity. Thus, the momentum is directly proportional to the mass of the object. If the mass of an object is somehow doubled, the momentum is doubled as well.
