... an object depends on the mass of the object and the amount of force applied. 1. Force=Mass*Acceleration (F=ma, a=F/m, m=F/a) 2. The harder you push something, the more it accelerates. 3. The more mass something has, the harder it is to accelerate. 4. These relationships are proportional. 2x Force me ...

An equivalent statement of the first law is that : An object at rest will stay at rest, and an object in motion will stay in motion at constant velocity, unless acted upon by an unbalanced force. This, at first, do ...

... • Newton’s Laws of Motion are: (1) Acceleration (or deceleration) occurs if and only if there is a net external force. (2) a = F/m [Note this is a vector eqn.] (3) The force exerted by a first object on a second is always equal and opposite the the force exerted by the second on the first. F12 = ...

... these forces. In each case the tension force of the cord attached to the salami must be the same in magnitude as the weight of the salami because the salami is not accelerating. Thus the scale reading is mg, where m is the mass of the salami. Its value is (11.0 kg) (9.8 m/s2) = 108 N. 19. (a) Since ...
