Flight
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
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.
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
Spear
How do birds produce thrust?
Birds produce thrust through the flapping of their wings.
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
Explain how a hot air balloon moves
lighting a flame
How did adding paperclips to the front of our paper airplanes impact their flight?
-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.
