Mass and Weight

Question 1

Mass

Answer 1

Measure if amount of matter in a body, kilogram (kg)

Question 2

Gravitational field

Answer 2

A region in which mass experiences a force due to gravitational attraction

Question 3

Gravitational field strength

Answer 3

Gravitational force per unit mass placed at a certain point

Question 4

Weight

Answer 4

The gravitational force acting on an object that has mass, Newton (N)

Question 5

What to use to measure mass

Answer 5

1. Beam balance
2. Calibrated electronic balance

Question 6

What to use to measure weight

Answer 6

Spring balance

Question 7

Relationship between mass and weight

Answer 7

Weight = mass × gravitational field strength
W = mg
Directly proportional

Question 8

Mass vs weight

Answer 8

Mass - measure od amount of matter
Weight - amount of gravitational force

Mass scalar, weight vector
Mass independent and wight dependent on gravitational field strength

Question 9

Inertia

Answer 9

Property of an object that resists changes from its state of motion or rest (mass–> measure of inertia)
