Part -1: Energy

1) Define Work and Power. What are their units?

2) What is the difference between Kinetic Energy and Potential energy? Give an example

3) Describe the Conservation of Energy by a circus diver example.

4) What are the similarities and differences between the Kinetic Energy and Momentum?

Part -2: Rotational Motion

1) Define the relationship between Rotational speed and Tangential speed

2) What is torque?

3) What is center of mass and center of gravity? Are they the same point or different points?

4) What is the difference between Centripetal Force and centrifugal force?

5) Define Angular Momentum. Give an example of Conservation of Angular Momentum

Part -3: Gravity

1) Why the Gravity is called the Universal law of Gravitation?

2) Write down the Gravitational Force equation.

3) What is the value of the Universal Gravitational Constant (G)?

4) How did Professor Cavendish measure the value of G first? Used two spheres attached to end rode and a thin wire suspending the rod.

5) Define the Inverse Square Law of Gravity and Distance.

6) Explain why the Ocean tide is influenced more by the moon than by the sun.

Distance of moon to earth is lesser as compared to that of sun.

Part -4: Projectile and Satellite Motion

1) What is a Projectile motion? Give two examples

2) What is the velocity of a Satellite that can keep it in the Earth's orbits without hitting the ground or escaping away from the earth?

3) What is the value of escape velocity?

4) Why the Satellite stays in orbit for such a long time without heading towards the earth?

5) Define Kepler's three Laws of Planetary Motion
