kinetic energy of object=1/2 (mv2 )
mass of that object remains constant through out the motion so K.E. remains constant..
if some how mass decreasing then by formula we can see that the kinetic energy will also decrease.

Kinetic energy increases as?
Kinetic energy increases as speed or mass increases, or as potential energy decreases.Velocity increases(The kinetic energy of an object would also increase as its mass increases, but this doesn't usually happen.)
As kinetic energy increases what happens to mass and velocity?
it speeds up
How is the acceleration of a mass changes if the force applied to it increases or decreases?
Acceleration increases when force increases and decreases when force decreases.
What happens to the kinetic energy of a snowball as a rolls across the lawn and gains mass?
That depends on what happens to its speed. The formula for kinetic energy is:KE = m(v)^2, in which m is mass in kg and vis speed in m/s.If either the mass or the speed increases, the kinetic energy will increase. So if the mass of the rolling snowball increases, but the speed remains constant, its kinetic energy will increase.However, in reality, due to friction between the snowball and the ground, the speed will decrease until the snowball stops. So the kinetic energy under natural conditions would decrease, even though the mass increases.

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 an objects kinetic energy as its velocity increases?
Kinetic Energy increases as velocity increases. Kinetic Energy = 1/2 * Mass * Velocity2
What will be the effect on kinetic energy by dubbling the mass?
the defining equation for kinetic energy= 1/2 mv2therefore kinetic energy is directly proportional to mass or as kinetic energy increases, mass increases proportionally (and vice versa).therefore if mass is doubled, the kinetic energy is also doubled.
Kinetic energy increases as?
Kinetic energy increases as speed or mass increases, or as potential energy decreases.Velocity increases(The kinetic energy of an object would also increase as its mass increases, but this doesn't usually happen.)
Is kinetic energy increases as mass increases is that ture?
Kinetic energy for nonrelativistic speeds is 1/2 times mass times speed squared. If ONLY the mass increases, then the kinetic energy will also increase.
What happens to the kinetic energy when an object moves faster?
it gets greater because the greater the mass the greater kinetic energy
What forms of energy a ball has when tossed up and down?
Potential Energy = mass * gravity * height. The higher the ball, the greater its PE. . Kinetic Energy = ½ * mass * velocity. The ball slows down as it goes up. As it goes up it, Kinetic energy decreases. . Kinetic energy decreases as potential energy increases. And the reverse is true as the ball comes down. The total energy (PE + KE) remains constant
As the mass of an object moving at a given speed decreases its kinetic energy does what?
Decrease, if its velocity is held constant. Because p = mv, a smaller m results in a smaller p if v is the same. decrease
How does increasing mass effects kinetic energy?
Increasing mass increases kinetic energy. The formula for KE = 1/2mv2, where m is mass in kg and v is velocity in m/s. KE is directly proportional to both mass and velocity, so if either one increases, so does the KE.
How is kinetic energy affected by a change in velocity?
Kinetic energy increases with an increase in velocity and decreases with a decrease in velocity. KE = 1/2mv2, where m is mass in kg, and v is velocity in m/s.
What 2 things increase as kinetic energy increases?
Generally speed. But also, if the obect is for example travellin up, the potential energy also increases.
How does velocity have an effect on kinetic energy?
The summation of potential and kinetic energy of an object is constant. When the potential energy of an object decreases the kinetic energy increases. Assume a falling stone from some high point above ground. At the beginning, the potential energy is maximum while the kinetic energy is minimum or zero. While the stone is falling, the kinetic energy increases while the potential energy increases (with the summation of both is constant). When the stone reaches the ground, the kinetic energy is maximum and the potential energy is zero.
