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.

Particles in gases are very far apart and there is a negligible amount of attraction force between these particles. Gas molecules have to move a long way before they interact and collide with other molecules. Sound energy slows down and does not move face when the molecules are not in contact with each other.
No. It cools at a rate proportional to the difference between its temperature and that of it's surrounding. The cooler it gets, the closer it will get to room temperature, and the cooling slows down.
No.
Friction is the force that slows down moving objects by opposing their motion through contact between surfaces. This resistance arises due to the contact between the surfaces of the moving object and the surface on which it is moving.
Friction is actually a force that resists motion between two surfaces in contact, not one that speeds it up. It acts in the opposite direction to movement and slows down objects in motion.
FRICTION .......... friction
Gravity actually accelerates the motion between two objects in contact with each other. The more massive an object, the stronger the gravitational force it exerts on other objects. This force can cause objects to accelerate towards each other when in contact.
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.
The force that slows or stops motion when objects rub together is called friction. Friction occurs when two surfaces are in contact and it acts in the opposite direction of the motion, creating resistance that opposes the movement.
The type of friction that slows down a sliding object is kinetic friction. It occurs between two objects in contact when one (or both) of the objects is in motion. Kinetic friction opposes the direction of the object's motion, leading to a decrease in its speed.
Friction slows down the motion of objects.
An unbalanced force that slows down moving objects is called a frictional force. Friction opposes the motion of objects and causes them to slow down due to interactions between the surfaces in contact.
During motion, the force of friction acts to resist further movement of objects. Such objects are always in contact with others or through air.
False. (Electromagnetic forces stop the motion.)
