Friction
friction
No.
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.
Force that resists motion is frictional force, viscous drag
I. Aristotle's Theory of Motion • Two basic principles: I. No motion without a mover in contact with moving body. II. Distinction between: (a) Natural motion: mover is internal to moving body (b) Forced motion: mover is external to moving body
friction
The force that resists motion between objects that are in contact is called friction. One object can be stationary or they both can move.

no
The property of objects that resists changes in motion is called inertia.
Friction between surfaces.
