The Newton's law of motion

• What is the Newton $1^{st}$ Law of Motion?


  A body will remain at rest or continue to move with constant velocity as long as the forces acting on it are balanced.
• What is the Newton $2^{nd}$ Law of Motion?


  Force = Mass x acceleration
• What is inertial Mass?

  Inertial Mass is a measure of how difficult it is to change the velocity of an object
• What is the Newton's $3^{rd}$ Law of Motion? 


  When body A exerts a force on body B, body B exerts an equal and opposite force on body A
• How can you measure reaction times?

  With the ruler drop test
• What does it mean if your reaction time increases?

  It has taken you longer to react to the situation
