kinematics Flashcards
What is a vector?
A line, a quantity with both direction and magnitude
Vectors include quantities like velocity, acceleration, and displacement.
What is a scalar?
A quantity with only magnitude, no direction
Scalars include color, temperature, mass/volume, and speed.
Can vectors be added together?
Yes, if they are the same quantity
For example, velocity can be added to velocity.
Define scalar.
A quantity with direction or magnitude.
Define vector.
A quantity with both magnitude and direction.
What is distance?
A measurement between two points; length measured.
Define displacement.
Change in position; distance from the starting point.
What is speed?
Distance covered in an amount of time, measured in miles/hour.
Define velocity.
Speed with direction; position over time.
What is acceleration?
Change in velocity over time.
What does the slope of position/time represent?
Velocity.
What does the slope of velocity/time represent?
Acceleration.
