The only thing that matters is the RELATIVE Velocity between the two Objects, not whether they are BOTH moving or not. If one is standing still and the other going 100 MPH, the result is the same as if both were going 50 MPH.
Frictional force exist between two moving objects that make it hard for them to move.Frictional force causes objects to slow down if force is not applied continuously to the moving objects. Frictional force causes some of the energy to be converted into the wasteful form of energy.
Objects move if they have momentum. Momentum is gained via an applied force. Therefore objects start or stop moving when a net force is working on them.
The force that opposes motion when moving objects over a surface is called friction
The force that decreases the acceleration of two objects moving against each other is the gravitational force.
gravity is a force that pulls object toward each other
The mass of the most objects is too small to cause a force large enough to notice. This is why you don't see the objects moving toward each other.
Centripetal force
