Kinematics Flashcards
Vector quantity
A physical quantity that has both magnitude and direction
Scalar quantity
A physical quantity that has only magnitude
Resultant vector
A single vector that has the same effect as the original vectors acting together
Distance
the length of the path traveled
Displacement
The change of position
Velocity
The rate of change of position/displacement
Speed
The rate of change of distance
Acceleration
The rate of change of velocity
An important aspect when using equations of one dimension
If dropped the initial velocity is 0
When asked the difference between two objects of different mass but the same height, what will be the same for them as they hit the ground, and how I get there
I can just cancel all the options that have mass or by looking at the equations of one dimension and notice that all of them are not influenced by mass only acceleration, displacement, time, and velocity.
Then asked a question with a graph and and having a principle or law what must I do
Use them to determined question
5 primary examples of scalar and vector respectively
Energy, Temperature, Time, Mass & distance and displacement, weight, Velocity, Force & acceleraction
Two ways to determine a resultant
1.Drawing with scale
2.Calcultation by determininding direction
