Motion in One Dimension
x = x f - x i
Average Velocity V avg = x/ t v avg = (x f – x i )/(t f – t i )
Velocity has magnitude and direction (25 mph west) Speed has only magnitude (25 mph)
Finding Velocity Graphically Slope = rise / run = y / x V avg = x / t
position (m) time (s)
Acceleration the rate of change of velocity a avg = v / t
Since velocity has magnitude and direction and a avg = v / t acceleration has magnitude and direction
Finding Acceleration Graphically Slope = rise / run = y / x a avg = v / t
velocity (m/s) time (s)
Distance (m) photo over 2 s Red ball Displacement? Average velocity? Average acceleration?
with constant acceleration v avg = x / t = (v i + v f ) / 2 x = ½(v i + v f ) t
Motion and Force A. Motion 1. Motion is a change in position
Analysis of a Distance vs. Time Graph
A graph of the instantaneous velocity of an object over a specified period of time Time is independent (x-axis) Velocity is dependent (y-axis) Remember,
Kinematics Demo – Ultrasonic locator Graph representation.
Constant Velocity. Recap Fun With Cars Terms Scalar Distance Speed Vector Displacement Velocity.
Acceleration Chapter 2 Section 2.
Uniform Motion. 1) Uniform (rectilinear) motion a) Constant Speed b) straight line c) same direction 2) Speed a) Distance covered in a period of time.
Motion in 1 Dimension Physics: Chapter 2-1 Pages
Motion in One Dimension. Velocity can be interpreted graphically The velocity of an object can be determined if the object’s position is known at specific.
Chapter 2 Motion in One Dimension 2-1 Displacement and Velocity Motion – takes place over time Object’s change in position is relative to a reference.
Concept Summary Batesville High School Physics. Projectiles A projectile is an object moving in 2 dimensions under the influence of gravity. For example,
Displacement vs Time, Velocity vs Time, and Acceleration vs Time Graphs.
DESCRIBING MOTION: Kinematics in One Dimension CHAPTER 2.
Graphical Look at Motion: displacement – time curve The slope of the curve is the velocity The curved line indicates the velocity is changing Therefore,
Acceleration- Change in Velocity
You will need 1-Journal 2-One piece of lined paper Please identify the lines on the graph at your desk.
Graphing Motion, Speed and Velocity. Graphs of Motion A Distance vs. time graph that is a straight line always means the object moves the same.
Which line represents the greater speed? Graphing motion The greater the speed, the steeper the slope.
