Momentum

Question 1

Friction

Answer 1

Resistance to motion that one surface or object encounters when moving over another surface.

Question 2

Inertia

Answer 2

Object’s tendency to resist change in its velocity

It is proportional to amount of material in an object.

Question 3

SI Unit of Inertia

Answer 3

kilograms (kg)

Question 4

System

Answer 4

Any object or group of objects that can be separated from surrounding environment.

Question 5

Isolated System

Answer 5

System with no external interactions

Question 6

Momentum

Answer 6

Product of the inertia and velocity of an object

p = mv

Question 7

Conservation of Momentum

Answer 7

Momentum can be transferred from one object to another but it cannot be created or destroyed.

pi = pf

Question 8

Impulse

Answer 8

The change in momentum of a system

J = change in p

Question 9

Momentum Laws & Isolated System

Answer 9

Any change in momentum in one object is made up by change in momentum (same magnitude) in the opposite direction of the other object.

Change in p1 + Change in p2 = 0
J = 0
