Force and laws of motion
Assignment based on topic Newton's second law of motion, momentum, direction of force and law of motion, unit of force, Impulse of a force
1. State Newton's second law of motion. Show that force is equal to the product of mass of the body and acceleration produced in the body.
2. Define momentum of a body. What are the units of momentum?
3. How is the change in momentum related to the force?
4. Write the Sl and non-SI units of force.
5. Why does a fielder pull his arms back while trying to stop/catch a cricket ball.
6. Calculate the force of gravity acting on a body of mass 1 kg. Take acceleration due to gravity, g = 9.8 m/s2
7. Which would require greater force - accelerating -a 10 g mass at 5 ms or at 20 g mass at 2 m/s2
8. Show that the Newton's first law of motion is contained in the second law of motion.
9. What is an impulsive force?
10. What is meant by the impulse of a force.
