1. 5 . FRICTION Engineers in particular have a real "love-hate" relationship with friction . Like the tortoise in the famous story, friction always "wins," eating away at energy you put into motion , slow and steady. Sooner or later, friction will cause the motion to stop . Ultimately, friction wins!

2. Definition Force that resists the movement of two contacting surfaces that slide relative to one another Acts tangent to the surfaces at points of contact with other body Opposing possible or existing motion of the body relative to points of contact

3. Types of friction Static Friction –The frictional force that prevents two surfaces in contact from sliding past each other. Sliding Friction –The force that acts in the opposite direction to the motion of a surface sliding on another surface.
