IB Physics SL A 2 4 Resultant Force From Diagrams Questions

Practise resolving forces to decide when objects are in translational equilibrium, including ladders, slopes and charged spheres.

Exam points

Resolve forces into components or combine force vectors from a diagram to determine the magnitude and direction of the resultant.
Test whether the vector sum is zero and use that result to identify translational equilibrium, including coplanar three-force systems.
Use force geometry and equilibrium equations to determine an unknown tension, component or contact force on slopes, ladders and suspended charged bodies.
Interpret a non-zero resultant in curved or constrained motion, including identifying the force direction required for circular motion.
Distinguish a zero resultant from zero individual forces and explain what the resultant implies about acceleration or constant velocity.
