Newton’s laws

• What does Newton's first law state about an object at rest?

  An object at rest will remain at rest unless acted upon by a resultant force.
• What is required to change the motion of an object according to Newton's first law?

  A resultant force is required.
• What happens to stationary objects with a resultant force of zero?

  They remain stationary.
• What happens to moving objects with a resultant force of zero?

  They carry on moving at the same velocity.
• What occurs when a non-zero resultant force acts on an object?

  It will cause the object to accelerate.
• What are the possible effects of a non-zero resultant force on an object?


  1. Stationary object starts moving
  2. Moving object speeds up
  3. Moving object slows down
  4. Moving object stops
• What is the formula to calculate force?

  Force = mass × acceleration.
• What is inertial mass?

  How difficult it is to change an object's velocity.
• How does mass relate to inertia?

  The more massive an object is, the more force is needed to change its velocity.
• How do u find the Inertial mass of an object?

  Inertial mass = Force / acceleration.
• What is the formula for force?

  F = ma
• How is acceleration defined in terms of mass and force?

  Acceleration is the force divided by mass, $a =$$\frac{F}{m}$.
• What factors determine the movement of an object?

  An object will move more if it has a large force applied or a small mass.
• Why does a small object move more compared to a large object when the same force is applied?

  Because it has less mass, resulting in greater acceleration.
• What is newtons third law?

  When two objects interact, they apply a force on eachother that are equal and opposite from the other object.
• What is Newtons second law?

  The acceleration of an object is directly proportional to the resultant force acting on it.
• What is Newtons first law?

  Velocity of an object changes if there is a resultant force.
