1. What are Newtons three laws of motion?
2. A Saturn V moon rocket has a total mass of 2.8 x 106Kg and 5 F1
engines each of which produces 6.69x106N of thrust and each of
them burned 2577Kg of fuel per second.
1. What is the acceleration of the rocket at lift off?
2. What g force did the crew experience?
3. At 142 seconds into the flight the centre engine of the 5 was shut down

, Angular Momentum what is

Angular momentum (L) is the quantity of rotation of a body, which i
the product of its moment of inertia (I) and its angular velocity (ω).
The leads to the questions what is angular velocity? and what is
moment of inertia?
