Forces
This is a push or pull on an object that can change its motion.
What is a Force?
You push on a 20-kg box with 100 N. According to Newton’s Third Law, the box does this with the same magnitude
What is pushes back on you with 100 N?
When an object is thrown, the path it follows is called this.
What is a Trajectory?
This force must overcome weight for a plane to take off.
What is lift?
This force opposes motion when two surfaces rub against each other.
What is Friction?
This equation denotes Newton's 3rd Law of Motion
What is F1 = F2
Every action (force) has an equal and opposite reaction
Velocity is this type of measurement.
What is a Vector?
These 2 components are measured as the 'Weight' force of an object
What are Gravity and Mass?
The wings push air downward to create lift. The air does this in response.
What is pushes the wings upward?
This equation represents Newton's 2nd Law of Motion
What is F=m*a ?
This quantity describes how far an object travels in a certain amount of time without considering direction.
What is Speed?
This is the formula for pressure
What is P = F/A
If thrust increases while drag stays the same, the airplane does this.
What is accelerates forward?
Newton's Laws:
A jet engine expels gases backward with a force of 120,000 N. According to one of Newton’s laws, the forward force on the airplane is...
What is 120,000 N?
A 10,000-kg airplane is flying at a constant speed of 250 m/s. Its acceleration is...
What is 0 m/s²?
When you decrease the area over which a force acts, pressure does this.
What is increases?
These are the forces that must be greater than their perpendicular counterparts in order for a plane to land.
What are Drag and Weight?
When mass remains constant, this quantity is directly proportional to net force and inversely proportional to mass
What is acceleration?
Physics:
The velocity of a car is measured as 30miles per hour.
What is the equation that denotes velocity (v)?
What is v = d/t
d= distance, t=time
"miles per hour" in mathematical form.
This constant represents the acceleration due to gravity.
What is 9.81m/s^2 ?
