Topic 2.4: Newton’s First Law
Learning Objective: 2.4.A
Describe the conditions under which a system’s velocity remains constant.
Essential Knowledge: 2.4.A.1
The net force on a system is the vector sum of all forces exerted on the system.
Essential Knowledge: 2.4.A.2
Translational equilibrium is a configuration of forces such that the net force exerted on a system is zero. Derived equation:
Essential Knowledge: 2.4.A.3
Newton’s first law states that if the net force exerted on a system is zero, the velocity of that system will remain constant.
Essential Knowledge: 2.4.A.4
Forces may be balanced in one dimension but unbalanced in another. The system’s velocity will change only in the direction of the unbalanced force.
Essential Knowledge: 2.4.A.5
An inertial reference frame is one from which an observer would verify Newton’s first law of motion.
