Resultant ForcesConceptual concept
Check understanding
- Explains what a vector quantity is and why force is a vector
- Calculates the resultant force when two forces act in the same or opposite directions on an object
- Explains what happens to an object's motion when forces are balanced vs unbalanced
- Draws free body diagrams showing all forces on a stationary object (e.g. a book on a table)
“If your child was pushing a heavy box along the floor but it wasn't moving, could they explain all the forces acting on it and why it stays still even though you're pushing?”
