Notes

Albert I.O.

do some Albert in for the Holidays!  No seriously get ranked take a screen shot of your -# 1 seed.
I will be awarding credit for activity/ accuracy 1->5

Momentum

Start with this

The Mechanical Universe: 15. Conservation of... by physics-lnr

• Read chapter summary 
• Read the chapter

• 1.     What factors affect the collision of two objects?

  2.     How can you determine if a collision is elastic or inelastic?

  3.     How can changes in momentum be used to determine the net force applied to an object?

   

• By the end of this unit, students will know: ·         Perfectly elastic collisions of objects moving in arbitrary directions ·         The effect of impulse at an arbitrary angle to initial velocity ·         Inelastic collisions of objects moving in arbitrary directions ·         Collisions: Perfectly elastic, perfectly inelastic, inelastic ·         Conservation of momentum with objects moving in arbitrary directions By the end of this unit, students will be able to: Describe the relationship between impulse and momentum Use conservation of momentum to solve problems Understand the differences between different types of collisions How to find the center of mass of an object

   

Theres a hole?

This problem envolves some relevant concepts and skills that will be required throughout the year.

• Gravity.  Constant and Variable.
• Work done by a variable force.
• Creating thought experiments to explain events.
• Derivation of calculus expresions 
• creating meaningful equations from graphs
•  You should me able to identify all critical points in the problem
• ZEROS
• MAXIMUMS

Centripetal Force

After studying the material of this chapter, you should be able to:
1. Calculate the centripetal acceleration of a point mass in uniform circular motion given the radius of the circle and either the linear speed or the period of the motion.
2. Identify the force that is the cause of the centripetal acceleration and determine the direction of the acceleration vector.
3. Use Newton's laws of motion and the concept of centripetal acceleration to solve word problems.
4. Distinguish between centripetal acceleration and tangential acceleration.


Friction:

1. Know the difference between static and kinetic friction   
• Be able to Graphically show the relationship between them
2. Measure coefficient of static friction from experimental data collected                           
3. Measure coefficient of kinetic friction from experimental data collected                                                                 
4. Define expected trends in the different frictional coefficients for different types of surfaces
