Newton's First Law (Law of Inertia) correct answers An object in motion (or at rest) will tend to stay in motion (or at rest) until it is acted upon by an outside force. Interia correct answers The tendency of an object to resist a change in velocity whether the object is in motion or motionless kinetic friction correct answers when the surface of one object slides along the surface of another object, static friction overcome. size of the friction force increases with an object's weight....

LAB 3: FORCE EVALUATION Texas A&M University College Station, TX 77843, US. Abstract This lab report will be covering the general concept of static friction and kinetic friction. With the usage of camera and interface with computer we will find out these forces. One will use a small piece of wood (in rectangle shape) with two different surfaces on both sides and that wooden pieces will be dropped from certain angle to get the values of static friction and static kinetic. Along with these...
