What is the relationship between friction and velocity?
2 answers:
- Friction is typically unrelated to speed. When the surfaces start to melt or otherwise change because of heat build up or inability to follow the surface then things will change.
- Friction is related to velocity in that it acts to reduce velocity. In other words it causes moving objects to decelerate.
- The friction force may also act as one of the forces in a moment that is causing motion. If the motion is rotary, or following any path, then the friction force may be simply a part of the system of forces that influences motion.

Answer:
For every action, there is an equal and opposite reaction.
Explanation:
Let's say I threw a ball on the wall. The image shows the instance the ball comes into contact with the wall.
If you would look at the image above,
- F1 and F2 are acting in opposite directions.
- They both have the same magnitude too.
F1 is the force of the ball on the wall (action force) and F2 is the force of the wall on the ball (reaction force). This is called an action-reaction pair.
