Generally it is transferred into heat and sound while the object is being pushed.
Kinetic energy is used to overcome friction and is dispersed as heat; some energy is converted to sound.
In any type of movement there is friction. This must be accounted for.
The total energy falls by a small amount which is used to overcome air resistance.
Some driving force is required.
Some of the force used in a lever will be to overcome friction, this means that not 100% of the force can be used to lever as some of it will be used to overcome friction as well as an multitude of other forces.
Friction :) it says so in in my science book.
Kinetic energy or the energy of motion is used which is then transformed to heat energy.
Mechanical energy is used, and thermal energy is produced
Some of the energy is converted from the motion of the bodies to sound and heat when it is used to overcome friction between the two bodies.
It's mostly converted to heat. Some of it can be used for the physical work of wearing down the surfaces causing the friction, depending on the hardness of the surfaces and their friction coefficient.
Friction is good because it provides traction. Friction is necessary for people to stand, or for vehicles to accelerate or break. Friction can also be used to convert kinetic energy to heat or electrical energy. Friction can be bad because kinetic energy is can be lost to friction.
A car accelerates when the engine produces more power than what is needed to overcome friction. The car reaches its maximum speed (on the level) when all the engine power is being used to overcome friction.
