PHY 2020 Lecture Notes - Lecture 4: Net Force, Resultant Force, Terminal Velocity
Document Summary
Acceleration depends on net force newton"s 2nd law. An outside force is acting upon it. Kick the ball and it accelerates: in the picture there is no acceleration on the ball because no force (foot) is acting up it, an 1-kg rock is thrown at 10 m/s straight upward. To reach the force of a heavier object, you have to force harder. Three identical blocks are pulled, as shown, on a horizontal frictionless surface. Hint: the blocks are connected -> all have the same (cid:498)a(cid:499) comes in two (cid:498)flavors(cid:499) static and kinetic (cid:523)sliding(cid:524: hw question #4, static, when stuff is at rest and their friction. Tires with groves to displace and redirect water from between the road surface and underside of the side. Friction is always opposed to the direction of motion. Equal and opposite to sanjay"s push less than sanjay"s push. Air resistance depends on the shape and velocity of the object.
