Vectors and scalars Flashcards
1
Q
What is a scalar?
A
Scalars are physical quantities that only have a magnitude but NO direction.
2
Q
What does magnitude mean?
A
It means size or extension of something.(It can be measured with number).
3
Q
What is a vector?
A
Vectors are physical quantities that have magnitude and direction.
4
Q
What is velocity?
A
It’s speed in a particular direction.
5
Q
What is the difference between vectors and scalars?
A
Scalars have only magnitude but vectors have magnitude and direction both.
6
Q
What are the two different quantities?
A
Scalars and vectors.
7
Q
In which quantity do speed and distance belong?
A
Scalars (because they don’t give any direction).
8
Q
In which quantity do velocity and displacement belong?
A
Vectors (because they have magnitude and direction).
