PHYSICS FINAL EXAM SAR Physics AM Kolchin I. Mechanics 1. Newton’s Second Law : The net force on an object is equal to the object’s mass times its acceleration, or F net = m * a 2. Newton’s Third Law : When one object exerts a force on a second object, the second object exerts an equal and opposite force on the ﬁrst object. 3. The pressure on an object is equal to the force on the object divided by the area over which the force is applied: P = F/A 4. The impulse applied to an object is deﬁned as the force on the object times the time during which it is applied, or: I = F Δ t 5. The impulse applied to an object equals the change in momentum of the object: F Δ t = m Δ v 6. The work done on an object equals the amount of force on the object (that is in the direction of its motion) times the distance moved by the object. W = F * d 7. Power is the rate at which work is done: P = Δ W/ Δ t . 8.
