P6 Definitions Flashcards
Description of motion
Kinematics
Explaining motion
Dynamics
described by a vector that points
from a common reference point to the actual location of the
object in space.
Position
a vector that points from an object’s
initial position to its final position
Displacement
a scalar quantity that states when and how long
the motion occurs
Time
It is used in referring to a specific time an object is at a
particular point.
Time
refers to the time
rate change of an object’s
position between its initial
and final positions
Average Velocity
It represents the time
progression of an object’s
position.
Position Time Graph
velocity at a specific instant in time. It is the slope of the
tangent line in the x-t graph
Instantaneous Velocity
Average acceleration is
the slope of the line
joining v1 and v2
Velocity-Time Graph
Slope of line connecting x1 and x2, or the time rate change of object’s initial and final position.
Average Velocity
d/t
Average Speed
Constant acceleration of a body falling
Freefall
Rate of change of velocity with time
Acceleration
- Constant Acceleration
- Instantaneous Acceleration
- Average Acceleration
Uniform Acceleration
