What does not have the same units as the others Kinetic Energy Momentum Potential Energy or Work?
Momentum does not have the same units as the others. Kinetic energy is measured in joules, potential energy in joules, work in joules, but momentum is measured in kilogram meters per second (kg m/s).
When kinetic energy doubled what happens to momentum?
If kinetic energy is doubled, the momentum will remain the same. Kinetic energy and momentum are related, but momentum depends on mass and velocity while kinetic energy depends on mass and velocity squared. Therefore, doubling kinetic energy will not affect momentum.
When an action and reaction occur momentum is usually lost?
No. Total momentum before and after the collision is the same. Some kinetic energy can be lost - but not momentum.
How does kinetic energy change when the momentum is doubled?
Kinetic energy is directly proportional to the square of the momentum. Therefore, if the momentum is doubled, the kinetic energy will increase by a factor of four.
What is the mathematical relationship between momentum and kinetic energy of the body?
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

What vector in a system points in the same direction as the linear momentum vector?
The energy vector, cmV = cP. The energy vector is parallel to the Momentum vector.
If two different masses have the same kinetic energy their momenta is?
... different. Kinetic energy is proportional to the square of the speed, wherease momentum is proportional to the speed.
What is the momentum of marbles after collision?
The momentum of marbles after collision is the same as the total momentum before the collision, according to the principle of conservation of momentum. If no external forces act on the system of marbles during the collision, the total momentum remains constant.
How does the principle of conservation of energy and momentum apply to the dynamics of a closed system?
The principle of conservation of energy and momentum states that in a closed system, the total amount of energy and momentum remains constant. This means that energy and momentum can change forms within the system, but the total amount will always stay the same. This principle is important in understanding how energy and momentum are transferred and distributed within a closed system during dynamic interactions.
How is momentum related to energy?
Momentum is related to energy through the concept of kinetic energy. Kinetic energy is the energy an object possesses due to its motion, and it is directly proportional to the square of the object's momentum. In other words, the greater the momentum of an object, the greater its kinetic energy.
Compare and contrast elastic and inelastic collisions?
In elastic collisions, kinetic energy and momentum are conserved, meaning the total energy and momentum before and after the collision are the same. In inelastic collisions, kinetic energy is not conserved, and some of the kinetic energy is transformed into other forms of energy, such as thermal or sound energy. In both types of collisions, momentum is conserved.
Why does heavier object have a greater momentum if light and heavy object have the same kinetic energy?
Well, the equation for momentum is mass x velocity. So, p (momentum)= m x v. The equation for kinetic energy is m x v(squared)/2. Let's say that there are two objects. One is 50 kg, and the other is 30 kg. These objects can both have the same kinetic energy, even though one of them has a larger mass. The determining factor in them both having the same kinetic energy, even though one of them has a larger mass is because of different velocities. The 50 kg object has a velocity of 7 meters/second, and the 30 kg object has a velocity of 9.036961141 meters/second. If you do the math, they both have the same kinetic energy (about the same). 50 kg x 7 m/s = 350 kg x m/s. 30 kg x 9.036961141 = 271.1088342. There is an inverse relation between the momentum of an object and its mass. The mass is the factor that influences momentum more than the velocity; that is why an object with a greater mass will have a greater momentum than the one with a lesser mass, only if they both have the same kinetic energy.
How about if the velocity is doubled but the mass remains the same?
If the velocity is doubled while the mass remains the same, the kinetic energy of the object will increase by a factor of four. This is because kinetic energy is proportional to the square of the velocity. The momentum of the object will also double as momentum is proportional to velocity.
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.
