The amount of kinetic energy an object has depends on its mass and speed.
the object's mass and speed
mass and velocity
Kinetic energy is the energy of motion. Your touching finger has mass and is moving some meters per second, so that motion is kenetic energy.
Any object which is moving from a lower level to a higher level is converting kenetic energy (ie climbing a set of stairs for example) to potential energy. A car which has been parked at the top of a hill has used kenetic enegry to get up there and has potential to roll down to the bottom of the hill if the brake is released.
The atoms, molecules, and small particles in air have mass. Wind is the name we give to a moving mass of air. Moving masses possess kenetic energy. Some of this energy can be transfered by collision, to dust, dirt and other particles on the ground, so they are forced to move too. A leaf blower makes use of this principle.
1 electron-volt is a small unit of energy. It's the amount of energy gained or lost by the (amount of electric charge on one electron) moving through a (potential difference of one volt). 1 joule of energy is the same as about 6,241,400,000,000,000,000 electron-volts.
Kinetic energy is when it's moving. Potential energy is when the object is motionless.
Only if it is moving.
Kinetic energy is the energy of motion (of an object as a whole).
Yes. Any moving mass has kinetic energy.
The kinetic energy depends on the object's mass, and on its speed.
kinetic energy KE = 1/2 mv^2

The factors of the kinetic energy of a body depend on mass of moving body.
yes. KE=1/2mv2, mass is also a factor that can change KE
Always moving.
Energy wasted due to friction is converted mostly to heat.
Kinetic energy does not depend upon the phase of matter; it depends upon the amount of matter, and the speed with which it is moving. One pound of matter, whether gas, liquid, or solid, moving at a specific speed, has the same kinetic energy.
