5 -Transportation and Energy
What is the "Law of Conservation of Energy"?
There is always energy and there is never more or less, the energy just changes form. *eg. kinetic energy when you run makes your muscles warm, which is temperature energy*
Name all 4 internal forces
Compression, tension, torsion and shear
What celestial bodies are the only ones to emit light in our solar system?
Stars and the Sun (technically a star)
How many Canadian astronauts have there been since 1983?
14
What is an adaption? Provide an example in nature
A physical or behavioural change that helps a species survive (eg. camouflaged coats on mammals to blend into their surroundings)
What is the difference between kinetic energy and potential energy?
Kinetic -movement that creates energy (eg. running)
Potential energy - energy "at rest" (eg. sleeping)
What is the difference between a static load and a dynamic load?
Static - constant pressure on the structure that does not change (eg. the structure itself)
Dynamic - A force on the structure that moves or changes (eg. a truck crossing a bridge)

What is the study of biomechanics?
The understanding of how a living organism moves and interacts with the environment it lives in.
What are three types of energy resources that Canadians use in transportation?
Crude oil, electricity, biofuels
Turning a doorknob is an example of what kind of internal force?
Torsion
What planet has the most moons?

What is the strongest arch in the world?
The Roman arch
Which type of transportation energy is the only one that does not have fumes?
Electric
What part of a structure supports weight from the sides and from the top of the structure?
Beams
What is the difference between a meteoriod, a meteor and a meteorite?
Meteoriod - bits of space rock flying through space
Meteor - when the rock enters the Earth’s atmosphere (shooting stars)
Meteorite - When the rock lands on Earth
One day our galaxy will collide with the Andromeda galaxy and it will create a ________________.
Irregular galaxy
Why is Pluto not accepted as a true planet in our solar system?
Pluto does not orbit around the Sun, and therefore does not align with out orbiting solar system

What is the bottom part of a truss called?
The tie
During the first ever space walk, astronauts dropped a hammer and a feather at the same time. They hit the ground at the same time. This concludes that ________ is the true reason why some objects fall faster than others.
Air resistance
____________ measures how much gravity is pulling down on an object. This can change based on where you are.
_____________ measures the amount of matter in an object. This does not change no matter where you are.
Weight, Mass
