Study Notes
Force and Acceleration
-
Equal Forces: Two objects pushing each other exert equal and opposite forces (Newton's Third Law). The strength of the push is the same for both, regardless of their mass.
-
Unequal Acceleration: The object with less mass experiences a greater acceleration (Newton's Second Law). Acceleration is inversely proportional to mass. For example, if two objects experience the same force, the object with a smaller mass will accelerate at a greater rate.
-
Example: A 150 kg shot-putter and a 75 kg golfer pushing each other exert equal forces. The golfer, having less mass, will experience twice the acceleration of the shot-putter.
-
Motion after Contact: Without external forces (like friction), objects will maintain constant velocity in a straight line (Newton's First Law).
