First and second law

• Who formulated the First and Second Laws of motion?

  Isaac Newton
• In which century did Newton work out his laws of motion?

  The 1600s
• What are Newton's two most useful laws of motion?

  • First Law of Motion
  • Second Law of Motion
• What is the significance of Newton's laws of motion?

  They describe the relationship between forces and motion
• What is Newton’s first law

  Of the resultant force on a stationary object is zero the object will stay stationary. If the resultant force on a moving object is zero it’ll carry on moving at the same velocity (same speed and directio)
• What causes velocity to change?


  non-zero resultant force
• What will a non-zero resultant force always produce?


  Acceleration in the direction of the force
• What are the 5 forms of acceleration?


  Starting , stopping, speeding up, slowing down and changing direction
• What is the correlation in the larger the resultant force and the acceleration?


  The larger the resultant force, the more an object accelerates as force is directly proportional to acceleration
• What is acceleration inversely proportional to?


  Acceleration is inversely proportional to mass.
• What does the larger the mass do to an object’s acceleration?


  The larger the mass, the less the acceleration
• What is the equation for Newton’s second law?

  F= m x a (Force = mass x acceleration)
