Summary
This source introduces Forces as pushes, pulls, or twists; classifies them as Contact and Non-Contact Forces; and teaches force arrows, interaction pairs, and force measurement in newtons.
Core Ideas
- Forces change speed, direction, or shape.
- Drag and friction are contact/resistive forces; gravity is non-contact.
- Force arrows and free-body diagrams model forces on objects.
- Forces are measured using a newton meter.
