Position:
-Displacement-an object’s change in position; It’s the vector that points from the object’s initial position to its final position, regardless of the path actually taken.
-Denoted as: ∆s
-SI unit for displacement is the meter [∆s] = m.
Looking at Distance VS. Time Graphs:
Popular graph: Position-Versus-Time Graph
Speed and Velocity:
-Average speed-the ratio of the total distance traveled to the time required to cover that distance
Velocity-The single concept that embodies both speed and direction
-Velocity is speed plus direction.
-The magnitude of the velocity is the speed. The magnitude of the average velocity is not called the average speed
Acceleration:
Uniformly Accelerated Motion and the Big Five:
-The simplest type of motion to analyze is motion in which the acceleration is constant.
Additional Kinematic Graphical Aspects:
-Tangent-a line that touches a curved line at only one point
Qualitative Graphing:
Either two graphs represent something that is not moving.
Either two graphs represent an object moving at a constant velocity in the positive direction.
Either two graphs represent an object moving at a constant velocity in the negative direction.
Either of the two graphs represents speeding up in the positive direction.
Either of the two graphs represents an object slowing down in the positive direction.
Either of the two graphs represents an object slowing down in the negative direction.
Either of the two graphs represents an object speeding up in the negative direction.
Free Fall
-An object can fall experiencing only acceleration due to gravity.
