3.2 is mass same as weight

Question 1

mass

Answer 1

a measure of the mount of matter in a body and does not change its location

Question 2

SI unit of mass

Answer 2

kilograms (kg)

Question 3

weight

Answer 3

the gravitational force acting on an object that has mass (changes with location)

Question 4

SI unit of weight

Answer 4

newton (N)

Question 5

gravitational field

Answer 5

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

Question 6

gravitational field strength

Answer 6

defined as the gravitational force per unit mass placed at that point

Question 7

formula of gravitational field strength

Answer 7

weight(N)/mass of object (kg)

Question 8

relations between mass and weight

Answer 8

w=mg weight acting on an object is directly proportional to its mass

Question 9

acceleration of object free falling under gravity without resistance

Answer 9

resultant force (N)= mass (kg) x acceleration (m/s^2)

Answer 10

spring balance, bathroom scale, electronic balance

Question 11

how to measure mass

Answer 11

beam balance
