Types of forces

• Newton's second law states that the net force acting on an object equals the rate at which it changes momentum.
• The force on an object is the product of its mass and acceleration.
• Force = Mass x Acceleration
• What is weight?

  Force of gravity on an object
• What is Drag?

  General name for resistive forces
• What is thrust?

  driving force
• What is friction?

  When objects slide past each other
• What is upthrust/buoyancy?

  Attempts to push objects to the surface of a liquid
• What is air resistance?

  Resistance on an object moving through air
• What is tension?

  When a rope is stretched to the limit7
• What is reaction?

  When any force acts in automatically generates this type of force
• What is magnetic force?

  The force felt between magnets and magnetic materials such as iron
