Speed and Acceleration. Measuring motion. Measuring Distance. Meter – international unit for measuring distance. 1 mm. = 50 m. Calculating Speed. Speed (S) = distance traveled (d) / the amount of time it took (t). . S = d/t. Units for speed.

ByDescribing Motion. Section 2-1. Motion. Motion occurs when an object changes its position. Both Distance and Time are important in describing motion. Sometimes you know motion has occurred even if you didn’t see it happen. (mail truck)

ByGraphing Motion. Motion can be plotted on a graph by labeling the X-axis with TIME and the Y-axis DISTANCE. A point on a graph can show the location and speed of an object at a particular time . . Those points are: x (time) y (distance). DON’T WRITE THIS.

ByPosition vs time graphs. Of an object at rest. Describe what the object is doing at 1 second, 2 seconds, 3 seconds, etc.?. 5 m. 4 m. At 1 seconds the object is located 4 meters from the origin. 3 m. position. 2 m. 1 m. 0 m. 4 s. 2 s. 3 s. 5 s. 0 s. 1 s. time.

ByDescribing motion with Graphs. Position vs. Time Graphs. x-axis: Time y-axis: Position slope = velocity (slope = “rise” / “run”) horizontal line: at rest straight line: constant velocity positive slope = positive velocity negative slope = negative velocity curved line: acceleration.

ByDistance vs. Time. Analysis of a Distance vs. Time Graph. Determining the motion on a D vs. T Graph. Where did the object start? Which direction did it go? Where did the object stop? Is the motion uniform (constant)? Is the motion non-uniform (changing)?

ByNewton’s Law. Change: ----motion Two questions: ● How do we describe motion? We want to analyze the motion mathematically The mathematical description of motion is called kinematics. ● How do we explain motion? The explanation of motion in terms of its causes is called dynamics.

ByVelocity-Time Graphs. Velocity-Time Graphs. Velocity-time graphs are graphs that represent an object’s velocity versus its time. Time is marked on the horizontal axis and velocity is on the vertical. Like position-time graphs, velocity-time graphs are drawn with a line of best fit.

ByHow To Go Nowhere Fast…. Displacement, Velocity and Acceleration. More Trig…. Pythagorean Theorem To find an angle, you need the inverse trig function i.e. x = y = 1 What is r? ?. Dynamics & Kinematics. Dynamics is the study of motion and of physical concepts

ByKey Concepts What kind of motion does acceleration refer to? How is acceleration calculated? What graphs can be used to analyze the motion of an accelerating object?. Acceleration. Key Terms. Acceleration . What is Acceleration?. Everyday language – the process of speeding up

ByA Mathematical Model of Motion. Chapter 5 Sections 1 and 2. Objectives Quiz 4. Interpret graphs of position versus time for a moving object to determine the velocity of the object Describe the information presented in graphs and draw graphs from descriptions of motion

ByDistance-Time Graphs. EQAO loves these!. There is a sensor called a CBR that can hook up to a graphing calculator. It can make a graph of your distance from the wall over a minute or so of time. Plotting distance against time can tell you a lot about motion. Let's look at the axes: . 1. 1.

ByVelocity And Acceleration. Velocity: Both speed and direction of an object V=d/t. Acceleration: The rate at which velocity changes. Acceleration. Speed and Vector. A vector quantity has both magnitude (the amount of or how much of) and direction. Therefore Velocity is a vector.

ByDistance, Speed and Time. Speed = distance (in metres) time (in seconds). D. S. T. Dave walks 200 metres in 40 seconds. What is his speed? Laura covers 2km in 1,000 seconds. What is her speed? How long would it take to run 100 metres if you run at 10m/s?
