Topic 4.1: Linear Momentum
Boundary Statements official exam scope notes
- Unless otherwise stated, the general term “momentum” will refer specifically to linear momentum.
Learning Objective: 4.1.A
Describe the linear momentum of an object or system.
Essential Knowledge: 4.1.A.1
Linear momentum is defined by the equation
Essential Knowledge: 4.1.A.2
Momentum is a vector quantity and has the same direction as the velocity.
Essential Knowledge: 4.1.A.3
Momentum can be used to analyze collisions and explosions.
Essential Knowledge: 4.1.A.3.i
A collision is a model for an interaction where the forces exerted between the involved objects in the system are much larger than the net external force exerted on those objects during the interaction.
Essential Knowledge: 4.1.A.3.ii
As only the initial and final states of a collision are analyzed, the object model may be used to analyze collisions.
Essential Knowledge: 4.1.A.3.iii
An explosion is a model for an interaction in which forces internal to the system move objects within that system apart.
