Forces on a Kite

Gravity is the force that pulls everything down to the earth. Gravitational force pulls everything to the centre of the earth. The bigger the mass, the larger the gravitational force. Without gravity we would all float off into space.

Drag is the force that slows the movement of an object through air or water. As a moving object pushes the water and air out of the way, the water or air pushes back on the object. This drag force is always opposite to the way the object is moving. The drag force increases as the object moves faster.

Thrust is the force that moves an object. When flying a kite, the thrust comes from wind. The thrust must be stronger than the drag to make the object move.
In a plane, thrust comes from your legs.

Lift is the upwards force on the kite. Lift is created by air flowing around the kite. The different speeds of the air flowing around the kite make it lift into the air.

tamrerti


Long ago the sky was dark and had no stars.
Deep in Lake Taupo lived a scary taniwha who ate people when it was dark. One day Tamarereti woke up he felt really hungry. Tamarereti went out fishing and caught lots of fish. He fell asleep and his waka drifted to the other side of Lake Taupo.
Tamarereti was hungry so he cooked his fish. It was dark and he was scared of the taniwha, but he had an idea. On the beach lay many shiny pebbles.
Tamarereti gathered as many pebbles as he could hold and set off in his waka.  As he sailed back to his village, Tamarereti threw the shiny pebbles into the sky where they settled to become the stars of Matariki.

i love



On the first day of term we made kites. Miss King gave us no instructions and we could only choose three materials. All of us had problems creating our kites. Some of us gave up and some of us made something. No ones kite flew. We have lots to learn before we can make a kite that will fly.
