Week 5

 

  Main Objectives
bulletYou should be able to state all three of Newton's laws and the law of gravity.   You should be able to give everyday examples which illustrate each of Newton's laws of motion.
bulletGiven any two of force, mass, and acceleration, you should be able to find the other one.
bulletYou should be able to calculate the gravitational force between two objects. (But you don't need to memorize G.)
bulletYou should be able to explain why motion in a circle at constant speed is accelerated motion.  You should know what direction this acceleration is in and what properties of the motion determine the size of the force needed to produce this acceleration.
bulletYou should be able to explain the difference between mass and weight.
bulletYou should be able to explain what we mean when we say the Moon is falling around the Earth.
bulletYou should be to define:
bulletspeed
bulletvelocity
bulletacceleration
bulletmomentum
