SLOs of 9th Class Physics Notes For Chapter 3
- Define momentum, force, inertia, friction and centripetal force.
- Solve problems using the equation Force=change in momentum/change in time.
- Explain the concept of force by practical examples of daily life.
- State Newton’s laws of motion. Distinguish between mass and weight and solve problems using F= ma, and w = mg.
- Calculate tension and acceleration in a string during motion of bodies connected by the string and passing over frictionless pulley using second law of motion.
- State the law of conversation of momentum.
- Use the principle of conservation of momentum in the collision of two objects.
