Document Summary
If the net force on an object vanishes, that object will not accelerate: if the net force on an object does not vanish, that object will accelerate. Net force acceleration: two objects interacting exert equal & opposite forces on each other. Let"s review these in a bit more detail . Newton"s 1st law: a body at rest (in motion) continues at rest (in motion) unless acted upon by a net force. net = F if v = constant (e. g. v = 0) Object in motion stays in motion (at same velocity) An object of mass m acted on by a net force a experiences an acceleration with. 1 n = 1 kg " m s2. Net force: sum of all individual forces. When two bodies interact, the force of the rst object on the second is equal in magnitude and opposite in direction to the force of the second object on the rst.
