    Cards (21)

    • What is Newton's first law of motion also known as?
      Inertia
    • What does Newton's first law state about an object at rest?
      It stays at rest unless acted upon
    • What happens to an object in motion according to Newton's first law?
      It continues moving at constant speed unless stopped
    • If a football is on the ground, what must happen for it to move?
      It must be kicked
    • How does a car's motion illustrate Newton's first law?
      A car keeps moving until brakes are applied
    • What is inertia?
      • An object's tendency to resist changes in motion
      • Example: A stationary book remains still unless moved
    • What does Newton's second law explain?
      The relationship between force, mass, and acceleration
    • What is the formula for Newton's second law?
      F=F =ma ma
    • What does the variable *F* represent in the formula F=F =ma ma?

      Force applied to an object
    • What does the variable *m* represent in the formula F=F =ma ma?

      Mass of the object
    • What does the variable *a* represent in the formula F=F =ma ma?

      Acceleration of the object
    • What happens when you push a light shopping cart with a force of 10 N?
      It accelerates quickly
    • How does pushing a heavy shopping cart with the same force compare to a light one?
      It accelerates more slowly
    • What happens when you kick a football with a force of 20 N?
      It moves much faster
    • What are the key concepts of Newton's second law?
      • Force: A push or pull causing acceleration
      • Mass: Amount of matter in an object
      • Acceleration: Rate of change of velocity
    • What does Newton's third law state?
      For every action, there is an equal reaction
    • What happens when one object applies a force on another?
      The second object applies an equal force back
    • How does walking illustrate Newton's third law?
      You push the ground, it pushes back
    • What occurs during a rocket launch according to Newton's third law?
      Gases eject down, rocket moves up
    • What are the key concepts of Newton's third law?
      • Action force: Force applied by one object
      • Reaction force: Equal and opposite force exerted back
    • What are the key terms related to Newton's laws of motion?
      • Inertia
      • External force
      • State of motion
      • Action
      • Reaction
      • Equal and opposite
