Newtons Laws of Motions

• What is Newton's First Law of Motion?

  An object remains at rest or in motion
• What happens to an object if the resultant force is zero?

  The object continues in its current state
• If a stationary object has a resultant force acting on it, what will happen?

  The object will start to move
• What does inertia refer to in Newton's First Law?

  The tendency to maintain the same state of motion
• What is the formula for Newton's Second Law?

  F = ma
• What does inertial mass measure?

  How hard it is to change velocity
• If the same force is applied to a bowling ball and a golf ball, what will happen?

  The golf ball will accelerate more
• How does acceleration relate to resultant force?

  Acceleration is directly proportional to force
• What is the relationship between mass and acceleration?

  Acceleration is inversely proportional to mass
• What does Newton's Third Law state about interacting objects?

  They exert equal and opposite forces
• What happens when rocket exhaust is pushed downwards?

  It creates an upward force on the rocket
• How does a girl pushing on a wall illustrate Newton's Third Law?

  The wall pushes back with equal force
• What are the key concepts of Newton's Laws of Motion?

  • First Law: Objects remain in motion or at rest unless acted upon.
  • Second Law: F = ma; acceleration depends on force and mass.
  • Third Law: Equal and opposite forces in interactions.
