All About The Olympic Rings

In 7/8 OD we have been learning about what the Olympic rings mean and who designed them. The 5 rings represent the 5 continents of the world Africa, Asia, America, Europe and Australasia but not Antarctica because hardly any people live on Antarctica. A fun fact is that every single country participating in the Olympics has at least 1 color from the Olympic rings. The color of the rings are Blue, Black then Red on the top row and Yellow then Green on the bottom. Baron Pierre De Coubertin the co-founder of the modern Olympics designed the rings in 1912.

                                                                                

What Is Force?

In 7/8 OD lately we have been studying force for science. We have been learning what force is, what effects force has on objects and what is the unit used to measure force. Force is a strength or energy as an attribute or physical action or movement acting as a push or a pull. Force acting on an object might cause the object to change shape, start moving, stop moving or accelerate or decelerate and change direction. A Newton (NT or N) is used to measure force and a force meter or newton meter is an instrument used to measure force.

3 examples of force that we use everyday are...

1. Pulling a rubber band or balloon to stretch it and make it change shape
2. Kick a ball to make it accelerate
3. Gravity is always pulling s down preventing us from floating us up into space



Some examples of force

Frictional, Tension, Normal, Air Resistance, Gravitational, Electrical and Magnetic
