Pot Luck
100
Any object that moves through the air or space, acted on only by gravity (and air resistance, if any)
What is a projectile?
100
A push or pull on an object
What is force?
100
To every action, there is an equal and opposite reaction.
What is Newton's 3rd Law?
100
Inertia in motion; an object's mass multiplied by velocity.
What is momentum?
100
A quantity that shows both magnitude and direction
What is a vector?
200
Two vectors at right angles that add up to a given vector
What are vector components?
200
The rate at which velocity is changing or a change in a state of motion; change in velocity/time interval
What is acceleration?
200
A force on an object that is equal and opposite to the reaction force
What is an action force?
200
The amount of force on an object multiplied by the time interval the force is applied to the object
What is impulse?
200
Force that rubs between materials they move past each other
What is friction?
300
The process of changing a single vector into its component vectors which are at right angle to each other.
What is resolution?
300
The amount of force per unit of area
What is pressure?
300
Upward reaction force
What is lift?
300
The momentum of a system will remain the same before and after an internal interaction has occurred.
What is the law of conservation of momentum?
300
Objects at rest tend to stay at rest, unless acted on by another force.
What is Newton's 1st Law?
400
Another word for air resistance
What is drag?
400
Mathematically two values change in opposite directions
What is inversely?
400
A combination of forces which include the action force and reaction force
What is an interaction?
400
When objects collide without being permanently deformed and without generating heat
What is elastic collision?
400
A state where no physical changes occur
What is mechanical equilibrium?
500
Falls below an straight-line path, increases continually with time, and is equal to 5t^2 meters.
What is vertical distance?
500
The acceleration produced by a net force on an object is directly proportional to the magnitude of the net force; acceleration = net force/mass.
What is Newton's 2nd Law?
500
Describes the reaction force in a gunshot
What is recoil?
500
The impulse required to brig an object to a stop and then to "throw it back again" is greater than the impulse required to bring the object to a stop.
What is bounce?
500
Total distance covered by an object divided by time
What is average speed?
