Labelling forces

  1. 1. Labelling Forces Correctly!
  2. 2. What were the names of the forces you had on your vocabulary cards last week? This can be any driving force, it may be a push or pull, but it could be an engine which forces an object forward.This is a force which acts in water, it can slowobjects down, reducing the affect of gravity. This is a force which acts in the air, it can slow objects down when they are moving against it. Or if harnessed could be used to move an object along.
  3. 3. This force acts on objects when they are in contact with a surface, such as the ground. It can be reduced by ensuring both surfaces are smooth.This force affects every object on Earth. It is aforce which pulls everything to the centre of theearth. This is an upward force which acts in water, it acts on a object against gravity, and is why certain objects float.
  4. 4. What forces are acting on this car which is driving along?This force is always This acts against the car,present. It goes towards as it moves forward and isthe centre of the earth, so acting against thewill always be pointing from propulsion.the top of the object This is the most powerful This force is only present force, this should be your where the car is in contact largest arrow, it should be with the floor, it acts against pointing in the direction the the propulsion. car is going …
  5. 5. What forces are acting on this duck floating in the water – it’s NOT moving?This force is always What do youpresent. It goes towardsthe centre of the earth, so notice aboutwill always be pointing fromthe top of the object these forces? This acts against the force of gravity to allow the duck to float.
  6. 6. Now it’s your turn … You are going to have 6 different objects which you need to label correctly. These are things I will be looking for:• Choose all the correct forces you think are acting on the object .• Make sure arrows show clearly which force you think is most powerful.• Your arrows should be pointing in the correct direction (the direction of the force) and should be in the correct place on the diagram.
