1. Momentum of an object determines the impact it has on another object when the two collide. Collisions can be elastic and inelastic. Applying forces at various points of an object can make it spin (that is due to torque). Objects at the state of rest or moving (and adding) with constant velocity are at the state of equilibrium. All force, energy and work considerations (including the principle of energy conservation) can be expanded to include rotational motion. Linear momentum...

Explain how a child "pumps" on a swing to make it go higher? On the basis of the law of conservation angular momentum, discuss why a helicopter must have more than one rotor (or propeller). Discuss one or more ways the second propeller can operate in order to keep the helicopter stable. A wheel is rotating freely about a vertical axis with a constant angular velocity. Small parts of the wheel come loose and fly off. How does this affect...

To apply the principle of angular impulse and momentum to
describe a particle's motion.
The moment of a force about a point O, fixed in an
inertial coordinate system, MO, and the angular momentum about the
same point, HO, are related as follows:
∑MO=H˙O
where H˙O is the time derivative of the angular momentum,
HO=r×mv. Integrating this equation with respect to time yields the
following equation:
∑∫t2t1MO dt=(HO)2−(HO)1
This equation is the principle of angular impulse and momentum,
and it...
