Academics

Q. 1. What physical quantities can be represented by vectors? Why? How do you determine the resultant force of the various forces acting on an object?

2. A 100-kg object is lifted to an altitude of 1000 km. What is the weight of the object on the ground? Does it have the same mass and weight at 1000 km? Explain.

3. Discuss the relationship between velocity and the acceleration. Which Newton's law best describes the motion of an object? State that law, and explain the relevant parameters involved. Can you give a numerical example?

4. A car is moving at a speed of 100 mph and rounds a corner at a speed of 100 mph. Is the car maintaining the same speed and the same velocity?

5. An acorn and a tree leaf fall from the same height at the same time. Which one reaches the ground first and why? How is free fall applied in this case?

6. State Newton's third law, and give some examples on how it is applied.

7. What is momentum of a truck speeding down the highway at a given instant? Discuss how the momentum is changed if the truck loses some of its cargo while maintaining the same velocity?
