(Acceleration)

• Newton's second law of motion


  The acceleration of an object is directly proportional to the net force on it and inversely proportional to its mass
• Greater mass of object

  Greater force needed to accelerate it
• Force = Mass x Acceleration
• Acceleration = Sum of forces / Mass
• Mass = Sum of forces / Acceleration
• Unit of force: Newton


  Amount of force that will accelerate a 1 kg mass at 1 m/s^2
• Calculating force for rocket acceleration

  Force = Mass of rocket x Acceleration required
• Calculating acceleration of ball hit with force

  Acceleration = Force / Mass
• Calculating mass of encyclopedia

  Mass = Force / Acceleration
