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.
A particle's kinetic energy is [1/2] times [particle's mass] times [particle's speed]2.
Since the KE is proportional to the speed squared, if the speed increases by a factor of 3,
the KE increases by a factor of (3)2 = 9.
Time is not a factor, speed is velocity and velocity equates to kinetic energy. E=Mass * Velocity squared.
kinetic energy, K.E = 1/2 mv^2 that is, it is directly proportional to mass, assuming velocity to be constant and is directly proportional to square of velocity assuming mass to be constant.
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.
No, not at all. Kinetic energy is energy related to movement - any moving object has kinetic energy; at low (non-relativistic) speeds, the kinetic energy is calculated as 0.5 x mass x velocity squared.No, not at all.

Kinetic energy is equal to potential energy during the change
The kinetic energy increases as the velocity increases (KE = 1/2mv2) until terminal velocity is reached, at which point the velocity becomes constant, and kinetic energy will no longer increase. The potential energy and kinetic energy will be at equilibrium, where PE = -KE.
Kinetic Energy increases as velocity increases. Kinetic Energy = 1/2 * Mass * Velocity2
The object has a mass of 2kg. When velocity is tripled the kinetic energy becomes 225 joules.
If speed/velocity is doubled and mass remains constant, then kinetic energy becomes quadrupled.

as you decrease the velocity of a car, you decrease the kinetic energy.
If the speed of an object doubles, its kinetic energy quadruples. This is because velocity is squared in the formula for kinetic energy.
particles speed up.
it speeds up
The kinetic energy will increase. Kinetic energy is defined by K=one half mv2 where m is the mass of the object, and v is the velocity of the object. The greater the velocity, the greater the kinetic energy. Since the velocity is squared, increasing it will cause the kinetic energy to grow much faster than if you increased the mass.
electrical energy becomes kinetic energy and sound energy
When you have kinetic energy, you must have a mass and a velocity since kinetic energy is half the product of the mass and the square of the velocity.
