Unit 2

A. Newton's Second Law
  • Can be defined as a=f/m
    • This is the same as a=f*/(1/m) 
  • Describes the relationship between acceleration and mass and the relationship between acceleration and force
    • Force is directly proportional to acceleration
      • This means that as force goes up acceleration goes up
    • Mass is indirectly proportional to acceleration
      • This means that as mass goes up acceleration goes down


B. Newton's Second Law Lab
  • In the first lab we manipulated the mass of the system by adding mass to the cart an leaving the force/mass of the hanger the same
  • As mass increased, the acceleration went down
  • When we graphed the line of the data we gathered, we found the slope to be .468 
  • The force from the hanger was .5N 
  • The reason why they are so close is because the force was the constant so it will also be the slope of the line
