Types of Force
What is force?
A push or pull on an object
What are the four forces of flight?
Lift, Weight, Thrust, Drag
What is a fluid?
Any materials that something can move through. (liquids and gases)
What is a contact force? Define and give an example.
A force that requires touch to act on an object. Examples may vary
How does force effect flight? (4)
Altitude, movement, speed, straight and level flight
What is buoyancy?
upward push exerted by the fluid on an object that opposes gravity. Helps objects float.
What is a non contact force? Define and give an example.
A force that acts on an object without touching it. Examples may vary. (magnets, static, gravity)
How do aerodynamics work?
We use aerodynamics to reduce the amount of drag on an object which makes it easier for them to fly.
What is density?
How tightly packed the particles in matter are.
What is an external force?
Any force acting on the object from the outside. Can be contact or non contact.All forces we talk about are external.
How does thrust in an airplane work? Hint: think about propellers or an engine.
As the propellers move or fuel is added to the engine, air passes through. As it is pushed backwards through the engine/propellers it causes an opposite force to thrust the plane forwards.
How does density of an object affect buoyancy?
If an object is more dense than the fluid it will be unable to float and therefore is not buoyant.
How does force affect an object's movement? (3)
Explain Bernoulli's Principle. (Hint: Think about lift and the airplane wings)
Bonus question: What is Ms.Chambers nephews name?
