  1. Newton’s 2nd Law Acceleration and Mass

  2. Newton’s 2nd Law Force = mass x acceleration - The acceleration of an object depends on its mass and the force applied to it.

  3. Newton’s 2nd Law Part 1 • Acceleration depends on mass (inverse relationship).

  4. Newton’s 2nd Law Part 1 • Pushed with same force, acceleration decreases as mass increases and vice versa.

  5. Newton’s 2nd Law Part 2 • Acceleration depends on force (direct relationship)

  6. Newton’s 2nd Law Part 2 http://www.ic.arizona.edu/~nats101/n2.html • As force on an object increases, acceleration increases

  7. Newton’s 2nd Law part 2 As force on an object decreases, acceleration decreases

  8. Force= Mass x Acceleration Equation for Newton’s 2nd Law Mass = Force / Acceleration Acceleration = Force / Mass

  9. Unit of Force • Newton (N)

  10. Rocket Videos • Same Force but different Masses • Results in greater acceleration for the smaller rocket

  11. Practice Problem • F=MxA • What force is necessary to accelerate a 1,000kg car at a rate of 40m/s/s? • 1,000kg x 40m/s/s= • 40,000N

  12. Practice Problem 2 • A=F/M • What is the acceleration of a 7kg mass if a force of 42N is used to move it toward Earth? • 42N / 7kg= • 6m/s/s
