Summary Lecture 6 Dynamics Newton’s 1st Law: If the net force on an object is zero an If the on an object is zero, an object originally at rest remains at rest, and an object in motion remains in motion in a straight line with const. speed. Net force: F net = Σ F acting on object Inertia: Tendency of a body to resist a change in its state of motion. Mass: Measure of the inertia of a body. The unit of mass is the kilogram (kg) The unit of mass is the kilogram (kg).

Unformatted text preview: Netwon’s 2nd Law: The acceleration of a body is directly proportional to the net force acting on it, and inversely proportional to its mass. F net = ma The direction of the acceleration is in the direction of the applied ne force the direction of the applied net force . Force: Force is a vector Force is a vector. Forces are measured in units of Newton (N). 1 N is the force required to accelerate a mass of 1 kg with 1 m/s 2 . 1 N = 1 kg m/s 2...
