Document Summary
Astronomy 2/9/16: motion, newton"s laws, angular momentum and. You are a shuttle astronaut returning after attempting to fix the iss with a hammer. As you are jetting back to your shuttle, your lifeline breaks, your jet runs out of fuel, your radio goes dead. To get back safely, you should: throw the hammer away from the shuttle (when you apply a force on the hammer, an equal force will be applied on you towards the shuttle) Angular momentum: depends on the geometry, the mass, and the rotational velocity of an object, angular momentum is conserved, a spinning wheel wants to keep spinning, a stationary wheel wants to keep still. 10. angular momentum is direction-dependent this means that the direction of the axis of rotation is significant and resistant to change everyday examples of the conservation of angular momentum. 14. a spinning ice skater figuring out orbital velocities with angular momentum.
