Types of forces

• Id the forces on an object are balanced, it will be stationary or travel at a constant speed
• Resultant forces change the speed, direction and shape of objects
• There are many different types of forces:

  normal force

  drag

  gravitational

  electrostatic

  weight

  tension

  magnetic

  thrust

  friction
• Vectors have direction and magnitude. Forces are vectors because direction matters. They differ from scalar quantities because scalar quantities only have magnitude
• Friction is a force that opposes motion
• Forces have effects on objects, such as changing shape, direction or speed
