Static or dynamic friction always act in a direction opposite to the impressed force. The dynamic friction does not need in any force. It is realy directed in opposit to the velosity.

However, you are right - dynamic friction forces can or slow down the movement of the body or accelerate it.
Shake, Lateral â A side-to-side vibration of the body, seats, and steering wheel. Shake, Vertical â An up and down vibration of the body, seats, and steering wheel. Shimmy, High-Speed â A vibration that causes the steering wheel to oscillate when driving on smooth roads at high speeds.tatic balancing removes only the lateral (side to side, wobble) imbalance and the tire and wheel assembly could possibly have a radial (up and down) vibration.
