Physics Newtons Laws Study Guide

Vocab

• Free Body Diagram: consists of a representation of a single body or a subsystem of bodies isolate from its surroundings that show all forces on it

• Net Force: sum of all the force that acts on an object. needs direction

• Force: a push or pull, any influence that tends to accelerate an object

• Force of Weight: downward gravitational pull exerted on an objects mass by a large body

• Frictional Force: resistance force that opposes the relative monitor attempted motion between 2 surfaces in contact. Frictional force is opposite of force applied

• Coasting Vehicle: a vehicle that is in motion, and is being slowed by frictional forces or air resistance, but does not have any Fa, or applied forces to off set Friction.

• Newton’s Second Law: the acceleration produced by a net force on a body is directly proportional to the magnitude of the net force, is in the same direction of the net force, and is inversely proportional to the mass of the body
