Motion Graphing Position vs. Time Graphs

The four kinematic equations which describe an object's motion are:

Acceleration (a vector quantity) is defined as the rate of change of velocity. It has units of m/s 2 Acceleration can be positive, negative, or zero. An.

Describing Motion with Position vs. Time Graphs The specific features of the motion of objects are demonstrated by the shape and the slope of the lines.

Preliminary Questions 2B.1.1: Position, Velocity, Acceleration Plots The plot to the right represents the motion of an object. During period 1, the object’s.

Things to know!. Velocity-Time Graphs A velocity-time (V-T) graph shows an object’s velocity as a function of time. A horizontal line = constant velocity.

IF WE MEASURE DISTANCE AND TIME, WE GET:

Velocity –Time Graphs.

Physics Chapter 5. Position-Time Graph  Time is always on the x axis  The slope is speed or velocity Time (s) Position (m) Slope = Δ y Δ x.

Diagrams and Motion Graphs.  The slope is equal to the acceleration.  Because we only consider constant acceleration, v/t graphs will always be straight.

Velocity-Time Graphs What is it and how do I read one?

MOTION - A CHANGE IN POSITION MEASURED BY DISTANCE AND TIME. SPEED - THE RATE AT WHICH AN OBJECT MOVES. VELOCITY - SPEED AND DIRECTION OF A MOVING OBJECT.

Chapter 4. Acceleration is the rate at which velocity changes. **Note: because acceleration depends upon velocity, it is a vector quantity. It has both.

STARTER During a road trip, in 6 hours you travel 300 miles. What is your average velocity? Average Velocity = distance travelled/time taken = 300 miles/6.

Scalars vs. Vectors Scalar – a quantity that has a magnitude (size) but does not have a direction. Ex. # of objects (5 apples), speed (10 m.p.h.), distance.

Interpreting Motion Graphs. Position vs. time graphs The slope of the graph is equal to the velocity The slope of the graph is equal to the velocity If.

Instantaneous Velocity The velocity at an instant of time. For a curved graph, use very small intervals of time.

Interpret The Graph. The graph shows an object which is not moving (at rest). The distance stays the same as time goes by because it is not moving.

Motion Graphing Acceleration vs. Time Graphs If graph has a SLOPE of ZERO; object has a CONSTANT ACCELERATION and VELOCITY is INCREASING. MOTION at a constant acceleration. slope = 0 Vav = increasing a = constant acceleration (m/s/s) time (s)

Motion Graphing Acceleration vs. Time Graphs If intervals between acceleration & time intersection points are same; graph represents object moving with INCREASING ACCELERATION; VELOCITY INCREASING greater slope = greater acceleration and velocity is increasing SIGN of slope on an acceleration/time graph indicates CHANGE IN ACCELERATION of object’s travel, or change in DIRECTION of acceleration when below axis POSITIVE (+) slope indicates increasing acceleration, or change in direction of acceleration when below x-axis acceleration (m/s/s) time (s)

Motion Graphing Acceleration vs. Time Graphs If intervals between acceleration & time intersection points are same; graph represents object moving with DECREASING ACCELERATION; VELOCITY DECREASING greater slope = greater acceleration and velocity is decreasing SIGN of slope on an acceleration/time graph indicates CHANGE IN ACCELERATION of object’s travel, or change in DIRECTION of acceleration when below x-axis NEGATIVE (-) slope indicates decreasing acceleration, or change in direction of acceleration when below x-axis acceleration (m/s/s) time (s)
