  1. Resultant force Resultant force : one force replacing the effect of several forces ( the force left over) 1. Zero Resultant force: * Object remains stationary if it was at rest Reaction weight Book on a table

  2. Resultant force Resultant force : one force replacing the effect of several forces ( the force left over) 1. Zero Resultant force: * Object remains stationary if it was at rest * Object continues to move at the same speed and in the same direction 2 m/s Moving marble on a smooth table Reaction weight Book on a table

  3. 1. Zero Resultant force: * Object remains stationary if it was at rest * Object continues to move at the same speed and in the same direction Car is going at full throttle and just stays at 70mph

  4. 1. Zero Resultant force: * Object remains stationary if it was at rest * Object continues to move at the same speed and in the same direction Car is going at full throttle and just stays at 70mph DRAG = 60 KN THRUST = ?

  5. 2. None zero resultant force: * object will accelerate or decelerate THRUST = 10 KN DRAG = 1 KN The plane accelerates at take off..

  6. 2. None zero resultant force: * object will accelerate or decelerate THRUST = 10 KN DRAG = 1 KN The plane accelerates at take off.. ...because thrust is larger than drag

  7. 2. None zero resultant force: * object will accelerate or decelerate THRUST = 10 KN DRAG = 1 KN The plane accelerates at take off.. ...because thrust is larger than drag When flying at constant speed at constant height thrust is greater than / equals / is less than drag.

  13. Object at the start Resultant force Effect on the speed at rest zero ? moving zero ?

  14. Object at the start Resultant force Effect on the speed at rest zero stays at rest moving zero ?

  15. Object at the start Resultant force Effect on the speed at rest zero stays at rest moving zero Velocity stays the same

  16. Object at the start Resultant force Effect on the speed at rest zero stays at rest moving zero Velocity stays the same moving Non zero in the same direction as the moving object ? moving Non zero in the opposite direction as the moving object ?

  17. Object at the start Resultant force Effect on the speed at rest zero stays at rest moving zero Velocity stays the same moving Non zero in the same direction as the moving object accelerates moving Non zero in the opposite direction as the moving object ?

  18. Object at the start Resultant force Effect on the speed at rest zero stays at rest moving zero Velocity stays the same moving Non zero in the same direction as the moving object accelerates moving Non zero in the opposite direction as the moving object decelerates
