BIO325H5 Lecture Notes - Lecture 2: Net Force, Arthropod, Seismic Wave
Document Summary
1. thelaw of inertia: an object in motion will remain in motion unless acted upon by a net force. The inertia of an object is its reluctance to change its motion. its harder to stop a whale. 2. the law of acceleration : the acceleration of a body is equal to the force applied to it divided by its mass, as summarized in the equation f= ma, where f is the force mthe mass anda the acceleration. 3. the law of reciprocal action : to every action there is an equal and opposite reaction. If one body pushes on another with a given force, the other will push back with the same force in the opposite direction. Drag-based swimming: rowing or paddling with limbs and newton"s 3rdlaw. A water boatman power-stroking its hind limbs rearward exerts an action force upon the surrounding water.
