• What is force measured in?

  Newtons (N)
• How would you calculate the resultant force if the forces act in the same direction?

  Add the forces together.
• How would you calculate the resultant force if the forces act in opposite directions?

  Subtract the forces from each other
• What is inertia?

  Resistance in an object to a change in its motion that gets bigger with mass increase.
• What is the formula for Newton's second law?

  Force = mass × acceleration
• What is mass?

  A measure of how much 'matter' an object has.
• What is weight?

  A measure of how large the force of gravity is on an object.
