### How does mass and velocity increase or decrease kinetic energy?

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 are the two parts of kinetic energy?

The non-relativistic equation for kinetic energy is mv^2/2 where
mass is m and velocity is v. The relativistic kinetic energy
equation is m/(1-(v^2/c^2))-m where m is mass, v is velocity and c
is the speed of light. The two variables which determine the
kinetic energy of an object are mass and velocity.

### What is an object with a lot of kinetic energy in its molecules?

The kinetic energy is the energ due to flow now we cannot find
any objects kinetic energy and get the one which is highest because
the potential energy of the object determines its kinetic value .
The problem is that potential energy varies a lot and therefore you
cannot determine a particular objects kinetic energy.

### Can a single object have kinetic energy but no momentum?

No, an object cannot have kinetic energy and no momentum.
Here's the reason: Kinetic energy is the energy an object derives
from being in motion. If an object is moving, it has some non-zero
velocity. Momentum is the product of mass (which the object will
have) and velocity, which it must exhibit to have kinetic energy.
That is why an object cannot have kinetic energy with no
momentum.
