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.
When speed decreases, kinetic energy must alslo decrease.
when the mass and velocity is low.
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.

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.

Decreasing the mass or Decreasing the velocity
Decrease, if its velocity is held constant. Because p = mv, a smaller m results in a smaller p if v is the same. decrease
Kinetic Energy increases as velocity increases. Kinetic Energy = 1/2 * Mass * Velocity2
the speed will make the kinetic energy smaller.
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 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.
