AP Physics Momentum/Impulse Flashcards

8188449149	Linear Momentum	The quantity of motion of a moving body. Vector quantity. For various objects is the sum of the individual quantities.	0
8188449150	Impulse	The amount of force acting on an object times the time in which this force is acting.	1
8188449151	Perfectly elastic collision	Two objects collide and conserve their Kinetic Energy & momentum. Objects bounce off of each other.	2
8188449152	Perfectly inelastic collision	Two colliding objects stick together to become one; momentum is conserved, but Kinetic energy is not.	3
8188469389	Equation for momentum	p=m v	4
8188472479	Equation for impulse	J=Ft	5
8188474984	Units for momentum	kg m/s	6
8188480854	Units for impulse	N s	7
8188493578	Impulse -momentum theorem	Impulse is equal to the change in momentum	8
8188532938	Conservation of momentum	The total momentum of an isolated system is conserved (unchanged) after a collision or explosion as long as no external forces act on the system.	9
8188693784	Pool balls hitting each other, bat & baseball are examples of...	Elastic collisions	10
8188698188	Clay balls hit & remain stuck, cars crash & become tangled are examples of...	Inelastic collisions	11
8188728129	When objects collide in-elastically the Kinetic Energy is not conserved, where does it go?	Becomes heat and sound.	12
8188783286	The forces which act between the objects of a system.	Internal forces	13
8188789052	The forces that act on the objects of a system from outside the system. The agent of the force is not a part of the system.	External forces	14
8188818036	The point at which the total mass of a system of masses can be considered to be concentrated.	Center of mass	15
8188835026	Amount of time the impact lasts	time of impact	16
8188838047	How hard an object hits	force of impact	17
8188844339	Direction of momentum	Same as direction of velocity	18
8188850914	Term applied to a physical quantity that remains unchanged during interactions	Conserved	19
