When kinetic energy increases what happens to the mass and velocity?
Kinetic energy of a mass is directly proportional to two variables: its mass and speed. Many mistake kinetic energy as being proportional to mass and velocity; it is, in fact, mass and speed. (With all technicalities aside, the speed is the factor that matters in computing kinetic energy of an object or a mass). Kinetic Energy = 0.5mv2 (m = mass and v = speed of the mass) Therefore, if the speed of the object increases, the kinetic energy increases. If the speed of the object decreases, the kinetic energy decreases. Similarly, if the mass of the object increases while traveling, its kinetic energy increases. If the mass of the object decreases, the kinetic energy decreases. All has to do with the directly proportional relationship between the two variables and the kinetic energy.
What happens to kinetic energy of a body when its velocity becomes one third?
The kinetic energy of a body is (1/2)mv2, where m is mass and v is velocity. If the velocity were 1/3, then the kinetic energy would be (1/2)m(v/3)2, which is equal to ((1/2)mv2)/9, so when the velocity is decreased by a factor of 1/3, its kinetic energy is decreased by a factor of 1/9.
Do changes in velocity and mass have the same effect on kinetic energy?
Kinetic energy is equal to one half the mass times the square of the velocity. Thus, changes in velocity and mass do not have the same effect on kinetic energy. If you increase the mass by a factor of 10 at the same velocity, you increase the kinetic energy by a factor of 10. However, if you increase the velocity by a factor of 10 at the same mass, you increase the kinetic energy by a factor of 100.
Which is not a factor in either kinetic or potential energy?
length
State any one factor which determines the kinetic energy of a body?
One factor affecting the kinetic energy of a particle (or body) in is the viscosity of the medium through which that particle moves
What happens to velocity if you double kinetic energy?
The square of 2 is 4. So, if the velocity doubles, the energy increases by a factor of 4.The square of 2 is 4. So, if the velocity doubles, the energy increases by a factor of 4.The square of 2 is 4. So, if the velocity doubles, the energy increases by a factor of 4.The square of 2 is 4. So, if the velocity doubles, the energy increases by a factor of 4.
How the kinetic energy of an object changes when the speed of the object doubles?
Look at the formula for the kinetic energy of an object: KE = 1/2 M V2Did you notice that " V2 " ? That means the KE is proportional to the squareof the object's velocity.So if the object's speed doubles, its KE increases by (2)2 = a factor of 4.

Describe the change in kinetic energy when the temperature of an object increases?
The more an objects kinetic energy increases the more it's temperature increases. An object that is traveling at 30 miles per hour will have a higher temperature than an object traveling at 10 miles per hour. This is in part due to friction. Mostly however, it is due to the fact that kinetic energy excites atoms in the object raising the objects temperature. You could put it like this: temperature = energy + atoms. Hope this helps.
What will happened to the ke if its velocity is reduced by 12 times?
Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.Kinetic energy is proportional to the square of the speed.

What happens to kinetic energy of a body when its velocity becomes one third?
The kinetic energy of a body is (1/2)mv2, where m is mass and v is velocity. If the velocity were 1/3, then the kinetic energy would be (1/2)m(v/3)2, which is equal to ((1/2)mv2)/9, so when the velocity is decreased by a factor of 1/3, its kinetic energy is decreased by a factor of 1/9.
When a velcity of a body is increased 5times what is the change in its kinetic energy?
The kinetic energy is proportional to the square of the speed. That means that if you increase the speed by a factor of 5, the kinetic energy increases by a factor of (5 squared).This applies to non-relativistic speeds; if you approach the speed of light, a different formula must be used.
What happens to kinetic energy if the velocity is tripled?
EXPLANATION:- We know that:- K.E = 1/2 m v^2 => K.E is directly proportional to the square of velocity. Conclusion:- If velocity becomes tripled than K.E. becomes Nine times to its initial value.
Do changes in velocity and mass have the same effect on kinetic energy?
Kinetic energy is equal to one half the mass times the square of the velocity. Thus, changes in velocity and mass do not have the same effect on kinetic energy. If you increase the mass by a factor of 10 at the same velocity, you increase the kinetic energy by a factor of 10. However, if you increase the velocity by a factor of 10 at the same mass, you increase the kinetic energy by a factor of 100.
What is the relationship between speed and kinetic energy?
The kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four. If there is a threefold increase in speed, the kinetic energy will increase by a factor of nine.
If the side of a square is doubled in size to 8 by what percent did its area increase?

What two factors determine an object kinetic energy?
Kinetic energy is given by the following equaiton: KE = 0.5*m*v^2 Where KE is kinetic energy, m is the object's mass, and v is its velocity. In other words, an object's kinetic energy is dependent on its mass and the square of its velocity. Note that since the velocity term is squared, velocity has a larger effect on kinetic energy than mass. For example, if you double mass, the kinetic energy will also double, but if you double velocity, kinetic energy increases by a factor of four.
