Expectations

SP2.a
Construct an explanation based on evidence using Newton's Laws of how forces affect the acceleration of a body.
- Explain and predict the motion of a body in absence of a force and when forces are applied using Newton's 1st Law (principle of inertia).
- Calculate the acceleration for an object using Newton's 2nd Law, including situations where multiple forces act together.
- Identify the pair of equal and opposite forces between two interacting bodies and relate their magnitudes and directions using Newton's 3rd Law.
SP2.b
Develop and use a model of a Free Body Diagram to represent the forces acting on an object (both equilibrium and non-equilibrium).
SP2.c
Use mathematical representations to calculate magnitudes and vector components for typical forces including gravitational force, normal force, friction forces, tension forces, and spring forces.
SP2.d
Plan and carry out an investigation to gather evidence to identify the force or force component responsible for causing an object to move along a circular path.
- Calculate the magnitude of a centripetal acceleration.
SP2.e
Develop and use a model to describe the mathematical relationship between mass, distance, and force as expressed by Newton's Universal Law of Gravitation.
