Weight And Mass

Question 1

Weight is a…

Answer 1

Force

Question 2

What is weight measured in?

Answer 2

Weight is measured in newtons (N)

Question 3

What is weight?

Answer 3

Weight is the downward pull of gravity on an object

Question 4

What does the weight of an object depend on?

Answer 4

The weight of an object depends on:

1. The object’s mass
2. How strong gravity is where the object is placed

Question 5

What is mass?

Answer 5

The mass of an object is the amount of matter making that object up

Question 6

Mass doesn’t…

Answer 6

Change

Question 7

What is mass measured in?

Answer 7

Mass is measured in kilograms (kg)

Question 8

Give the formula for working out weight.

State the units for each term.

Answer 8

W=MG
Weight = mass x strength of gravity

W is N
M is kg
G is N/kg

Question 9

What is the strength of gravity on Earth?

Answer 9

Strength of gravity on Earth = 10N/kg

Question 10

What is the strength of gravity on the Moon?

Answer 10

Strength of gravity on the Moon = 1.6N/kg

Question 11

Weight = ?
Mass = 2.80kg
Gravity = 4.00N/kg

Calculate the object’s weight

Answer 11

W=MG
W=2.80x4.00
W=11.2N

Question 12

Weight = 40.0
Mass = 4.00
Gravity = ?

Calculate the strength of gravity on the object
State which planet the object is on

Answer 12

W=MG
40.0=4.00xG
G=10N/kg

The object is therefore on Earth
