Forces
Forces
Gravity, non contact, A force that pulls objects towards the centre of the Earth.
Friction, contact, a force that resists the sliding or rolling of one solid object over another.
Magnetism, Non contact, A force that causes some metals to be to be attached to each other.
Drag, Contact, A force that opposes the movement of a solid
Electrostatic, Non contact, they pull or push on objects without touching them
Tension, contact, the pulling force since the ropes cannot push effectively
Buoyancy, Contact, a force which pushes on objects in liquids making them float.

Magnets
When the North Pole and the South Pole are placed together, the magenets are attached to each other.
When the North Pole and the North Pole are placed together, the magenets are replelling to each other

Floating and sinking
An object floats when the weight force on the object is balanced by the upward push of the water on the object. If the weight force down is larger than the upward push of the water on the object then the object will sink.
Friction
Whenever an object moves agents another object, a friction force is created. Friction force act in the opposite direction to the movement. Friction makes it more difficult for to move. There are two types of friction grip and slip.
