Force and laws of motion
Force, Newton's Law of Motion, inertia and mass, Newton first law of motion
1. What is force? What can a force cause?
2. What is the unit of force? How is force described graphically?
3. Is force a scalar or a vector quantity?
4. How are forces classified? Give one example of each.
5. Define balanced and unbalanced forces.
6. Under what condition a body is said to be under balanced and unbalanced forces?
7. Name the laws of motion put forwarded by Newton. What do these laws contribute to the field of science?
8. What is meant by inertia? Which of the following has more inertia?
(a) A plastic eraser or a pencil (b) A football or stone of the same size.
9. Why do passengers tend to fall sideways when the bus takes a sharp turn?
10. Why do passengers in a bus tend to fall backward when it starts suddenly?
11. How many types of inertia do the material bodies have?
12. State the Newton's first law of motion. How does this law define force?
