Core Idea - Motion and Stability: Forces and Interactions
[HS.PHY.2.10] - Use free-body force diagrams, algebraic expressions, and Newton’s laws of motion to predict changes to velocity and acceleration for an object moving in one dimension in various situations. Clarification Statements: Predictions of changes in motion can be made numerically, graphically, and algebraically using basic equations for velocity, constant acceleration, and Newton’s first and second laws. Forces can include contact forces, including friction, and forces acting at a distance, such as gravity and magnetic forces.
[AI.F-LE.A.1.b] -
Recognize situations in which one quantity changes at a constant rate per unit interval relative to another.*
[AII.N-VM.A.1] -
(+) Recognize vector quantities as having both magnitude and direction. Represent vector quantities by directed line segments, and use appropriate symbols for vectors and their magnitudes (e.g., v, |v|, ||v||, v).
[AII.N-VM.A.3] -
(+) Solve problems involving velocity and other quantities that can be represented by vectors.
[HS.PHY.2.2] -
Use mathematical representations to show that the total momentum of a system of interacting objects is conserved when there is no net force on the system. Clarification Statement: Emphasis is on the qualitative meaning of the conservation of momentum and the quantitative understanding of the conservation of linear momentum in interactions involving elastic and inelastic collisions between two objects in one dimension.
