Forces and Interactions

Newton's Second Law of Motion
Analyze data to support the claim that Newton’s second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration.

Conservation of Momentum
Use mathematical representations to support the claim that the total momentum of a system of objects is conserved when there is no net force on the system.

Reducing Force in Collisions Device
Apply scientific and engineering ideas to design, evaluate, and refine a device that minimizes the force on a macroscopic object during a collision.

Gravitational and Electrostatic Forces Between Objects
Use mathematical representations of Newton’s Law of Gravitation and Coulomb’s Law to describe and predict the gravitational and electrostatic forces between objects.

Electric Current and Magnetic Fields
Plan and conduct an investigation to provide evidence that an electric current can produce a magnetic field and that a changing magnetic field can produce an electric current.
