The "force" of friction is always exactly opposite the direction of motion.
The friction force is opposite in direction to the velocity.
By definition, friction is opposite of the direction of motion.
The direction of the force of friction is opposite of the direction of the motion.
It is in most cases opposite to the direction of motion.
The direction of the force of friction is such that it opposes the direction of motion that an object would move if there were no frictional force acting on the object.
How do you compare the direction of your partner's and your force?
Rubber will have a high coefficient of friction on most surfaces, but we cannot know whether there is more or less friction unless we have something to compare it to.
By using friction. Without it, they wouldn't have anything so the two will have also faults along the friction
the plane of polarization matches the vibrational direction of the electrons
well if you compare them together they are quite different velocity has a poo in your mouth and momentum like to wee on your dog in the morning, okayy!
All stars can be used to tell which direction you are travelling in as the movement of the earth is in a consistant direction, allowing you to compare your movement with the direction that the stars are travelling in.
Metric System
The coefficient of static friction is always larger because it takes more initial force to move an object that is at rest.
