Energy
Resources that are depleted over time because they will not be naturally replenished for thousands or millions of years.
Non-Renewable Resources
An upward force that acts to overcome the weight of a living thing or object and hold it in the air.
Lift
When the buoyant force is less than the weight of an object, the object will ______
Sink
What is the opposite force to thrust?
Drag
Hydropower is an example of a renewable resource or a non renewable resource?
Renewable
The ability to do work is called:
Energy
A force that can act in the direction of movement.
Thrust
True or False- if an object has greater density than the fluid it is placed in it will float
False- it will sink
True or false- Thrust is a force that acts in the direction of movement
True
What is one way that Alberta produces energy?
Alberta relies on both renewable and non-renewable energy resources to fulfill energy needs, including fossil fuels, water and hydro, wind, and biomass.
Materials that can be used to produce energy.
Energy resources
A force that can act in opposition to the direction of movement.
Drag
An upward force exerted by a fluid that opposes the weight of anything placed in the fluid.
Buoyant Force
Name one of the traditional technologies of flight we learned in class.
Bow and Arrow
Slingshot
Fishing Spear
How do birds produce thrust?
Birds produce thrust through the flapping of their wings.
A push or pull on an object is called
Force
An act or instance of passing through the air by use of wings.
Flight
True or false- the opposing force to buoyancy is drag
False- it is weight
Weight is the opposing force to what in flight?
Lift
What is Archimedes' principle?
A body at rest in a fluid is acted upon by a force pushing upward called the buoyant force, which is equal to the weight of the fluid that the body displaces. If the body is completely submerged, the volume of fluid displaced is equal to the volume of the body.
Resources that are not depleted over time as they can be naturally replenished if handled responsibly.
Renewable Resources
How did adding drag tabs to our paper airplanes impact their flight- 2 PARTS
-Slowed them down
-Shorter flight path
When the buoyant force of the fluid is greater than the weight of an object, the object will _____
Float
True or false- More lift = higher altitude.
True
What is Bernoulli's principle?
Bernoulli's principle states that as air moves around an object, it creates different pressures on that object. Faster air means less pressure. Slower air means more pressure. The key to flight is creating pressure upwards on the bird's wing to keep the bird in the air.
