Answer #1:

Kinetic energy is the energy possessed by an object due to its movement

or motion. Momentum on the other hand, is the quantity of motion of an

object that is a product of its mass and velocity.


Answer #2:

Kinetic Energy = 1/2 M V2kg-m2/s2 (Newton-meter = Joule)

Momentum = M V kg-m/s (Newton-second)

Numerical Difference = (1/2 M V2) - (M V) = (M V) x (1/2V -1) .

Is Linear Momentum a Vector?

Yes. That is the chief reason for the difference between momentum (a vector) and kinetic energy (not a vector).

What is the relationship between momentum and kinetic energy?

Kinetic Energy is mistakenly defined as a scalar energy. It is properly a vector energy EK= mcV where V is a vector. Momentum P = mV. Kinetic energy and momentum are related by c, EK = cP.

What is the difference between momentum and kinetic energy and why is it that kinetic energy can be changed in to other forms of energy but momentum cant?

Firstly, momentum is not a form of energy; the question seems to imply so. Kinetic energy is the energy possessed by a moving object. That energy is provided by a source, and can be removed from the object because energy possessed by an object is not an inherent part of that given object. Momentum is a property of mass; momentum is inherent in the mass of the object, and cannot be removed or put somewhere else, only altered.

What is the relationship between kinetic energy and momentum?

Kinetic energy is the sum of all the parts of momentum: p=mv >function for momentum ∫ p=∫ mv.dv >integrate both sides with respect to velocity ∫ p=.5mv²=Ek >results in formula for kinetic energy

How are momentum and kinetic energy related?

Kinetic energy = (momentum) x (1/2 of speed)

How will the momentum of a body changes if its Kinetic energy is doubled?

kinetic energy = p2/2m . if kinetic energy is doubled , then new momentum becomes root 2 times the original momentum

How do momentum and kinetic energy differ?

Kinetic Energy = KE = (mv^2)/2 momentum = P = mv --- Any object contain kinetic energy. This energy increases by momentum. If you hold a bullet, then it has got kinetic energy. When you drop it to the ground, this kinetic energy is released. By shooting the bullet out with a gun, the momentum increases the bullets kinetic energy drastically. It is in a way not the bullet that kills. it is the momentum of it that makes it a killer. Regards.

What is the difference is between momentum and inertia?

inertia is measured in energy 1/2 mv2 momentum is measured in Kilogram metres per second Kgm/s mv momentum can be thought of as the first derivative of kinetic energy dependent on velocity.

Can a single object have kinetic energy but no momentum?

No, an object cannot have kinetic energy and no momentum. Here's the reason: Kinetic energy is the energy an object derives from being in motion. If an object is moving, it has some non-zero velocity. Momentum is the product of mass (which the object will have) and velocity, which it must exhibit to have kinetic energy. That is why an object cannot have kinetic energy with no momentum.

What is the difference between energy and momentum?

Momentum is the product of mass and velocity. Energy is the capacity of a body to do work.

When kinetic energy doubled what happens to momentum?

Momentum increases

What is the mathematical relationship between momentum and kinetic energy of the body?

You can't calculate the kinetic energy if you only know the momentum. Both kinetic energy and momentum depend on mass, but also on the velocity - and the dependence is different. Kinetic energy is proportional to the square of the speed, momentum is proportional to velocity. You can solve the equations, to get energy in terms of momentum AND mass: (1) p = mv v = p/m (2) e = (1/2) mv2 Replacing (1) in (2): e = (1/2) m (p/m)2 e = (1/2) p2/m (e = kinetic energy; p = momentum) So, you see that (for a given mass), kinetic energy is proportional to the square of the momentum. HOWEVER, since it also depends on mass, two objects with the same momentum can have a different amount of kinetic energy.

Can a body have momentum without having kinetic energy?

No. Both momentum and kinetic energy involve velocity. In order for kinetic to be zero, the velocity would have to be zero. If the velocity is zero, then momentum is also zero.

What does not have the same units as the others Kinetic Energy Momentum Potential Energy or Work?


A collision in which kinetic energy may be transferred between the colliding particles but the total kinetic energy remains the same?

This is called an elastic collision. In this case both momentum and kinetic energy is conserved.

What is another name for kinetic energy?

momentum energy

The energy of motion is called?

Momentum. Or Kinetic energy

How is kinetic energy and momentum similar?

Kinetic energy is the energy created by movement. Momentum is the power that something gains through movement i.e pushing off the ground builds momentum. The movement of a ball rolling down a hill creates kinetic energy.

Does an object with energy always have momentum?

Not if it's potential energy. Only objects with kinetic energy have momentum.

What is the difference between kinetic mechanical energy?

Mechanical Energy is a type of kinetic energy. Kinetic energy is the type of energy which possesses in an object due to its motion.

Can you change kinetic energy without changing momentum?

No, momentum and kinetic energy for all classical particles depend only on their mass and their velocity. Due to the fact that momentum and KE both depend on the same factors, they cannot be changed independently. Kinetic energy = 0.5mv2 Momentum = mv

What is the energy during momentum?

There is no "energy during momentum". A moving object has both non-zero momentum, and non-zero kinetic energy.

If momentum is doubled then its kinetic energy is?

The relation between kinetic energy is proportional to the square of velocity. Momentum is directly proportional to velocity. If the momentum of an object is doubled, but its mass does not increase (so velocity remains well below the speed of light), then its velocity is doubled. If the velocity is doubled then the kinetic energy increases by the square of 2, or four time.
