Mechanics Flashcards
What is a vector
A physical quantity which has both magnitude and direction
What are some vector quantities
Displacement
Velocity
Force
Acceleration
What is the symbol to represent displacement and wha is it measured in
Δχ (m)
What is the symbol to represent velocity and what is it measured in
v (m.s^-1)
What is force measured in
N
What is the symbol to represent acceleration and what is it measured in
ā (m.s^-2)
What are three ways to show direction
To a given reference point
Bearing
Towards cardinal points
What is the formula for displacement
V=x/t
OR
x=v.t
What is the minimum resultant
The difference of two forces acting in opposite directions
What is the maximum resultant
They sum of two vectors working in the same direction
What is a scalar quantity
A physical quantity which has magnitude only
What are some scalar quantities
Magnitude Distance/length Mass Volume Time Speed
What is distance/ length measured in
m
