Assignment 24


Centripetal acceleration and centripetal forces are addressed.  The lab experiment tests conservation of momentum in the collision of two spheres.


qa problems address centripetal acceleration and centripetal forces.

One 'seed' question asks for the direction of a force that causes the velocity of an object to change in a direction making a right angle with its direction of motion, and asks what happens if this condition continues to apply.  Another problem applies momentum conservation to the collision of two marbles.

The lab activity attempts to verify conservation of momentum in the collision of two spheres, as revealed by the projectile behavior of the spheres after collision, and the relative masses of the spheres.

The text topic is motion in two dimensions, which includes among other situations motion on a circle and projectile motion.
