Weight And Mass Flashcards
1
Q
What is weight?
A
A force that a body experiences due to its mass and the size of the gravitational field strength that it is in
2
Q
Is weight a scalar or a vector quantity?
A
Vector
3
Q
What is weight measured in?
A
Newton’s (N)
4
Q
What is mass?
A
A measure of the amount of matter that is contained within a three-dimensional space
5
Q
Is mass a scalar or a vector quantity?
A
Scalar
6
Q
What is mass measured in?
A
Kilograms (KG)
7
Q
Is mass affected by the size of the gravitational field that it is in?
A
No
8
Q
How do you work out the weight?
A
Mass X gravitational field strength
9
Q
What does gravitational field strength depend on?
A
- the mass of the body
* the radius of the body
10
Q
A large mass and a small radius =
A
Large gravitational field strength
11
Q
What are the units for gravitational field strength?
A
N/kg or m/s2
