What is the displacement of an object when the kinetic and potential energies are equal?
If the Kinetic Energy and the Potential Energy of an Object REMAIN equal while the object is in Motion, then it is Moving at a Constant Velocity PARALLEL to its "Reference System".
Can two people be moving in different speed and have same kinetec energy?
Certainly, because kinetic energy is determined by both mass and speed. If I'm traveling at 1/2 the speed that you are, but I have 4 times as much mass as you have, then our kinetic energies are equal. And for an example in the other direction . . . If my mass is only 1% of yours, but I'm traveling at 10 times your speed, then our kinetic energies are equal. That's how a bullet or a baseball can knock a grown person off his feet. Kinetic Energy = 1/2 (mass) x (speed)2
Why if total momentum is zero but kinetic energy is not equal to zero?
This sounds like a trick question. Momentum has a sign (positive or negative), and if you have two masses that are going in opposite directions their total momentum is zero. But the sum of their kinetic energies is positive.
The total potential and kinetic energy of all microscopic particles in an object make up its?
The total potential and kinetic energy of a MICROSCOPIC object is it's INTERNAL ENERGY.
What happens to kinetic energy when you decrease the mass?
Kinetic energy = K.E. = 1/2 (m)(v)2. Since mass, m, is part of this equation, we see that two particles of equal velocity but of different masses have different kinetic energies. In the case of equal velocities, the particle with the lesser mass will have the lower kinetic energy. Remember that momentum is the derivative of K.E., and so the momentum of an object is also related to the mass of an object as well.
What happens if the particle of two substances have the same average kinetic energy?
the specific heats of the substances are identical the particels will not react chemically the substances have equal theraml energies the substances have equal temps hop it helped sorry if it didnt

Why the average kinetic energy of Neon Krypton and Radon are equal?
They are all monoportic gases, which all have the same average kinetic energy.

What makes up the the total potential and kinetic energy of all the microscopic particles in an object?
The sum of total energies of all microscopic particles is equal to the internal energy of that object.

How does kinetic energy of solids liquids and gases compare?
The kinetic energy is lowest in solids, higher in liquids, and highest in gases.
Two bodies of equal masses are moving with uniform velocities v and 2v.Find the ratio of their of heir kinetic energies?
Kinetic energy is equal to the mass of the object times the velocity squared (Ek=.5mv2). To obtain the ratio between the two objects, divide the first by the second (Ek1/Ek2). This is equivalent to .5m1v12/.5m2v22. Since the masses are equal, they cancel out and you are left with v12/v22. Next, as stated in the problem, the seceond velocity is twice as much as the first so plug that coefficient into the aforementioned equation. (1v12)/(2v22). Since the values of velocity (v) are equal in this problem, they can cancel out just as the masses did. Now, 12=1 and 22=4; so the ratio is 1/4.
What type of energy is sound energy?
The energy in a sound wave is both kinetic and potential.Just as in a vibrating spring, the medium has mass and moves and so moving mass is kinetic energy.Just as in the spring there is compression and rarefaction, so there is elastic potential energy.In fact, these two are equal, potential energy = kinetic energy, just like a spring.Just like in a vibrating spring, the total energy is constant and equal to the average kinetic energy plus the average potential energy.
At what temperature is the average kinetic energy of an atom in helium gas equal to 6.21 times 10-21 J?
300 k
