Topic 2.5: Newton’s Second Law

Learning Objective: 2.5.A

Describe the conditions under which a system’s velocity changes.

Essential Knowledge: 2.5.A.1

Unbalanced forces are a configuration of forces such that the net force exerted on a system is not equal to zero.

Essential Knowledge: 2.5.A.2

Newton’s second law of motion states that the acceleration of a system’s center of mass has a magnitude proportional to the magnitude of the net force exerted on the system and is in the same direction as that net force. Relevant equation: a⃗sys=∑F⃗msys=F⃗netmsys\vec{a}_{sys} = \frac{\sum \vec{F}}{m_{sys}} = \frac{\vec{F}_{net}}{m_{sys}}

Essential Knowledge: 2.5.A.3

The velocity of a system’s center of mass will only change if a nonzero net external force is exerted on that system.
