Unit 1 – Test Review
Write the mathematical expression for Object 1 Position = -2(m/sec)*time + 90(m) tIme (sec) Position (meters) 45 90
Predict the position at 100 seconds. Position = -2(m/sec)*time + 90m time (sec) Position (meters) x = meters
What is the same at the point where the objects intersect. AB The position
Are the velocities constant? AB Yes, it is a straight line.
Draw a motion map for each object on the same line. AB
What is the velocity at 17 seconds? -8 m/sec time (sec) Position (meters)
What is the velocity at 40 seconds? 2.6 m/sec time (sec) Position (meters)
What is the total distance travelled? 80 m time (sec) Position (meters)
What is the total displacement? 0 m time (sec) Position (meters)
Make a motion map. time (sec) Position (meters)
Look at the motion map below and make a position vs time graph x t
Unit Three Test Review Good Luck!. Sketch a motion map of object A x t A B.
Straight Line Motion Looking at position, velocity, and acceleration from the integral.
Section 1 p A change in position Motion occurs when something changes position relative to a point of reference.
Motion and Force A. Motion 1. Motion is a change in position 2. Reference points are necessary.
What is motion? An object is in motion when it’s distance from another object changes. What is a reference point? It is an object or place used to determine.
Preview Objectives One Dimensional Motion Displacement Average Velocity Velocity and Speed Interpreting Velocity Graphically Chapter 2 Section 1 Displacement.
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,
Objectives After completion, you should 1. Know the term displacement, velocity,acceleration and deceleration for motion in a straight line 2. Be familiar.
Representing Motion in a Variety of Ways Graphs: - Allows us to interpret motion without even seeing the motion occur What was the object’s velocity (not.
Graphical Analysis of Linear Motion. A car travels along a road at a constant velocity of 10. m/s time (s) position (m)
A change in position relative to some reference point during a period of time. Motion.
Warm Up A particle moves vertically(in inches)along the x-axis according to the position equation x(t) = t 4 – 18t 2 + 7t – 4, where t represents seconds.
Kinematics deals with situations involving motion. S=distance/displacement. If s=0, object is at starting point +- relates to position from a certain.
Chapter 2 Describing Motion: Kinematics in One Dimension.
Motion Graphs. Interpret The Graph Below: The graph shows an object which is not moving (at rest). The distance stays the same as time goes by because.
Constant Velocity The position increases by 2 meters every second. The position decreases by 2 meters every second.
Motion can be plotted on a graph by labeling the X- axis with TIME and the Y-axis DISTANCE.
The four kinematic equations which describe an object's motion are: There are a variety of symbols used in the above equations and each symbol has a specific.
V In the study of kinematics, we consider a moving object as a particle. Displacement Kinematics in One Dimension (Phy 2053) vittitoe.
Position-Time graphs. WHY GRAPH? What is the best way to describe motion of an object to somebody that did not witness it? With accuracy Can be understood.
August 15 Physics. Homework quiz A race horse runs with an average velocity of 12 m/s for 35 seconds. What is its displacement? If it crosses the finish.
Graphical Analysis Of Motion. Aims : Graphical Analysis To measure the motion of an object Construct a graph of distance vs. time Calculate the speed.
Kinematics: What is velocity and acceleration? Lets Review v = d t Distance traveled (m) Time taken (sec) Average Velocity (m/sec) Instantaneous Velocity:
Choose a category. You will be given the answer. You must give the correct question. Click to begin.
1 Which line shows a speed that gets faster & faster? VELOCITY A B C D E. None of the above.
Summarize things so far… Distance (m) Time (sec) What is the object’s speed from: 0-3 sec: 3-5 sec: 5-11 sec:
Motion Graphs Time Distance. Can you define: Motion is a change in position measured by distance and time Speed tells us the rate at which an object moves.
Acceleration! Chapter 9 Section 3. Acceleration Lets Review: What is Speed? Velocity? What is a Vector? Acceleration: RATE at which velocity changes Acceleration:
Position vs time graphs Of an object at rest. Describe what the object is doing at 1 second, 2 seconds, 3 seconds, etc.? position time 1 m 2 m 1 s 3 s2.
