Momentum Definitions

Question 1

linear momentum

Answer 1

the product of the mass and velocity of the object

Question 2

linear momentum statement

Answer 2

a vector and is the same direction as the velocity vector

Question 3

linear momentum equation

Answer 3

p=mv

Question 4

Newton’s second law

Answer 4

the net force acting on an object is equal to the rate of change of momentum

Question 5

Newton’s second law equation

Answer 5

Fnet=delta P / delta t

Question 6

isolated system

Answer 6

a system that has no net external force acting on it

Question 7

the law of conservation of linear momentum

Answer 7

the total linear momentum of an isolated system remains constant (is conserved)

Question 8

elastic collision

Answer 8

a collision in which both momentum and kinetic energy are conserved

Question 9

inelastic collision

Answer 9

collision in which only momentum is conserved

Question 10

impulse

Answer 10

the product of the net force and the contact time

Question 11

impulse equation

Answer 11

J=Fnet x delta t

Question 12

impulse statement

Answer 12

vector quantity and is in the same direction as the net force vector

Question 13

what is impulse equivalent to

Answer 13

change in momentum (J= delta P)

Question 14

impulse secondary equation

Answer 14

delta p = Fnet x delta t
