## Motion and Stability: Forces and Interactions

High School students who demonstrate an understanding of Forces and Interactions can:

HS-PS2-1.
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.

Activity: Rocket Sledder

Activity: Friction

Activity: Skydiving

Activity: Push It!

Activity: Coffee Filter Physics

Activity: Carts, Bricks, and Bands

Activity: Weightlessness Training

HS-PS2-2.
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.

Activity: Egg Drop

Activity: Inelastic Collisions

Activity: Elastic Collisions

Activity: Roller Coaster Loops

HS-PS2-3.
Apply scientific and engineering ideas to design, evaluate, and refine a device that minimizes the force on a macroscopic object during a collision.

HS-PS2-4.
Use mathematical representations of Newton’s Law of Gravitation and Coulomb’s Law to describe and predict the gravitational and electrostatic forces between objects.

Activity: Gravitational Fields

Activity: Name That Charge

Activity: Charge Interactions

Activity: Sticky Tape Experiments

Activity: Polarization

Activity: Coulomb's Law

Activity: Electric Field Lines

HS-PS2-5.
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.

Activity: None. Check back later. We have some resources planned.

HS-PS2-6.
Communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials.
