Chapter 5 Newton’s Second Law of Motion – Force and Acceleration

Acceleration = change in velocity Time Interval Net force – combination of all forces acting on an object Acceleration depends on net force If the net force on an object is 0. The object will stay at rest or stay at a constant velocity (Newton’s First Law) If there is a net force acting on an object that is greater than zero, it will experience an accleration The acceleration of an object is directly proportional to the net force: acceleration ~ net force

Acceleration = ____1____ mass Acceleration = ____net force____ a = F M

Friction There are several different kinds of friction: Static Friction Sliding Friction Rolling Friction Fluid Friction We will only focus on Static Friction and Sliding Friction

Static Friction – is the friction between two surfaces in contact with each other if they are at rest (FS) Sliding Friction – is the friction between two surfaces in contact with each other if they are moving (FK) Ff = μ x FN

The normal force (support force) will always act perpendicular to surface in contact:
