Vectors and Scalars Flashcards
How is force measured?
Newtons (N)
Are forces vectors or scalars?
Vectors
Do scalars have both direction and magnitude?
No, they only have magnitude
Do Vectors have both direction and magnitude?
Yes, for something to be a vector it must have both.
Is weight a scalar?
No it is a vector
it has both direction and magnitude
Is mass a scalar
Yes
It has no direction
What are some Scalar quantities?
distance, speed, energy, time, mass
These have no direction
What are some vector quantities?
forces, weight, velocity
How do you calculate weight?
mass x gravity = weight
What does the term mass mean?
mass is how many particles you are made up of.
What does the term weight mean?
Weight is the force you feel from gravity
How do you calculate distance?
speed x time
What is acceleration?
change in velocity to get faster/ speeding up
how do you calculate acceleration?
change in velocity
