|---|---|---|---|---|---|
| Stored energy due to height and gravity | show 🗑
|
||||
| The energy of motion | show 🗑
|
||||
| show | Energy cannot be created or destroyed; it only changes form
🗑
|
||||
| The distance something travels per unit time | show 🗑
|
||||
| Speed in a given direction | show 🗑
|
||||
| What type of quantity is velocity? Scalar or vector? | show 🗑
|
||||
| What makes velocity a vector quantity? | show 🗑
|
||||
| show | Vectors
🗑
|
||||
| The highest speed that can be reached by a falling object is its __________ | show 🗑
|
||||
| Terminal velocity is achieved when ____ | show 🗑
|
||||
| What happens as a plane climbs? | show 🗑
|
||||
| What happens as a plane dives? | show 🗑
|
||||
| show | A push or a pull on an object
🗑
|
||||
| What two things does a vector quantity have? | show 🗑
|
||||
| What are the 4 forces of flight, and in which direction do they act? | show 🗑
|
||||
| What do we call the force every object in the universe exerts on every other object? | show 🗑
|
||||
| show | 9.8 m/sec^2. All things, big and small, fall at this rate if there is not air resistance!
🗑
|
||||
| show | Gravity depends on mass and distance. The closer two things are the more gravitational force, and the bigger the more gravitational force. The earth is way more massive that us!
🗑
|
||||
| The force of gravity on the mass of an object gives us its ________. | show 🗑
|
||||
| show | Lift
🗑
|
||||
| What is the direction of lift? | show 🗑
|
||||
| "As airspeed increases, the pressure drops" is an example of what principle? | show 🗑
|
||||
| According to the Bernoulli principle, where is the pressure highest on a plane's wing? | show 🗑
|
||||
| show | The pressure above the wing is lower than the pressure below the wing (because air moves faster on top to cover a bigger distance), causing a net force upward (lift).
🗑
|
||||
| show | The sum of all the forces exerted on an object.
🗑
|
||||
| State Newton's 1st Law of Motion | show 🗑
|
||||
| What is inertia? | show 🗑
|
||||
| Objects with more ___ have more inertia. | show 🗑
|
||||
| show | An unbalanced force will produce a proportional acceleration. (That is, if an unbalanced force acts on an object, it will accelerate)
🗑
|
||||
| What is sometimes stated as "for every action there is an equal and opposite reaction? | show 🗑
|
||||
| show | The engine pushes exploding gases backwards, and the gases push the plane forwards (thrust).
🗑
|
||||
| When a propeller plane takes off, what action/reaction is at work? | show 🗑
|
||||
| show | A parked plane will not move unless an unbalanced force acts on it.
🗑
|
||||
| How is a plane in the air an example of Newton's 1st Law of Motion? | show 🗑
|
||||
| show | Drag
🗑
|
||||
| show | Drag slows down the plane and lessens fuel economy.
🗑
|
||||
| show | Drag acts along and opposed to the direction of flight.
🗑
|
||||
| What is thrust? | show 🗑
|
||||
| Apply Newton's third law to thrust from a propeller. | show 🗑
|
||||
| show | Pitch
🗑
|
||||
| What word is used to explain the movement of a plane's nose right and left? | show 🗑
|
||||
| When the plane rotates around the axis in the middle of the plane, we call that a _______ | show 🗑
|
||||
| What is stability? | show 🗑
|
||||
| What three design features help create stability? | show 🗑
|
||||
| When all forces acting on an object cancel each other, so the net force is 0, we call them this: | show 🗑
|
||||
| Unbalanced forces result in a net force in some _______. | show 🗑
|
||||
| When unbalanced forces act on an object, the object does this. | show 🗑
|
||||
| If a plane is flying level at a constant speed, what can you tell about the 4 forces of flight acting on it? | show 🗑
|
||||
| show | Newton's 1st Law of Motion: an object in motion remains in motion in the same direction at the same speed unless acted on by unbalanced forces.
🗑
|
||||
| show | Newton's 2nd Law of Motion: A net force exerted on an object will produce a proportional acceleration.
🗑
|
||||
| The rate of change in speed of an object (speeding up or slowing down) | show 🗑
|
||||
| Solve a practice problem (using 5 step method)What is the speed of a car that goes a distance of 125 km in 2 hours? | show 🗑
|
||||
| Solve a practice problem (using 5 step method) If a student takes 3 seconds to run to first base at an average speed of 6.5 m/s, what distance did she run? | show 🗑
|
||||
| show | 25 s
🗑
|
||||
| show | 05 m/s^2
🗑
|
||||
| Solve a practice problem (using 5 step method) If a water skier with a mass of 55 is pulled with a force of 110N, what will the acceleration be? | show 🗑
|
||||
| Solve a practice problem (using 5 step method) What is the weight of a 65 km student on earth? | show 🗑
