3. What are Newton's laws?
4. What is net force, and what does it mean?
5. How do you add and subtract forces?
6. How do you draw a force diagram?
7. What happens when multiple forces act on objects?
8. How do you represent multiple forces acting on objects with diagrams?
9. What is friction?
How can you tell if a force in a diagram is balanced or unbalanced?

Answer each question in order, answer in very short answer, don't explain just answer the questions in bold words

Answer 1

1. A force is a push or pull that can change an object's motion.
2. Magnitude indicates the strength, and direction indicates the line along which the force acts.
3. Newton's laws describe the relationship between forces and motion: 1) Inertia, 2) F=ma, 3) Action-reaction.
4. Net force is the total force acting on an object, determining its acceleration.
5. Add forces in the same direction; subtract forces in opposite directions.
6. A force diagram is drawn with arrows representing the magnitude and direction of forces.
7. Multiple forces can either balance (result in no motion) or unbalance (result in acceleration).
8. Use arrows representing each force's magnitude and direction, meeting at the object's center.
9. Friction is a force that opposes motion between two surfaces in contact.
10. If the net force is zero, the forces are balanced; if not, they are unbalanced.
