2 Today we will….Describe motion using Cornell notes, questions, and interactions.
3 1. Motion2. Motion – what is it? 3. When the distance from another object is changing 2. Example 3. Walking away from a chair 3. A car leaving the driveway
4 2. Reference point – what is it? 3. A place or object used for comparison to determine if something is in motion 3. Examples: 4. Tree 4. Chair 4. House
5 3. Use + or – to indicate change in position 3 3. Use + or – to indicate change in position 3. Think of the y and x axis 3. If you move up or to the right it will be a positive change 3. If you move down or to the left it will be a negative change 3. Train example
10 On your white board, determine the answer An object moves 3 cm to the right, then 6 cm to the left, then 8 cm to the right. What is the object’s final displacement from its origin? What is its distance traveled?
22 Person A begins the task card questions. STOPPerson A begins the task card questions.
23 2. Velocity (v) – what is it? 3. Speed (v) in a given direction 3. V is a vector 3. Magnitude and direction shown by the length and direction of the arrow. 3. Changes in velocity may be due to changes in speed, direction, or both
24 2. Real-life velocity examples 3. Weather – direction and speed of storms 3. Air traffic controllers – have to know V and direction of planes 3. Riding a bike around curves 3. Others?.....
26 Write your summary which must include the answers to your questions. 3 minute pauseUsing your task cards write 3 good questions. You may not start your question with “what is…?”Write your summary which must include the answers to your questions.
27 Homework2 strategies of your choice that involve vector, velocity, speed, and average speed.
28 Ticket out the Door Facts You/Opinion Velocity is speed in a given direction. Describe in detail what velocity is.Velocity plays a role in your daily life. Explain how velocity affects you and your daily activities. Use complete sentences.
29 Today we willDescribe acceleration using Cornell notes, NTG, task cards, and a Venn Diagram.
30 1. Acceleration –what is it? 2. Rate at which velocity changes with time 2. REMEMBER – a change in velocity involves a change in speed, direction, or both 2. Acceleration refers to increasing speed, decreasing speed, or changing direction
31 2 Increasing speed = acceleration 2. Decreasing speed = deceleration 2 2 Increasing speed = acceleration 2. Decreasing speed = deceleration 2. Changing direction = acceleration occurs any time the direction changes 3. Example – car going around a curve 3. Example – runner running around a track
32 2. Calculating Acceleration 3. Calculation of change in velocity per unit of time3. Acceleration (a) = Final V – Initial VTimea= Vf-Vit
33 ExampleCalculate the acceleration of an airplane if it’s initial velocity is 0 m/s and it’s final velocity is 40 m/s if it takes the airplane to reach this speed in 5 seconds.
34 ExampleAs a roller coaster car starts down a slope, its velocity is 4 m/s. But 3 seconds later, its velocity is 22 m/s in the same direction. What is its acceleration?
35 2. Graphing acceleration 3. Speed vs. time graph 3. Time goes on the x-axis 3. Velocity goes on the y-axis.
36 Practice TimeCreate a Venn Diagram to compare/contrast graphing velocity vs graphing accelerationPage 355 # 4 and 5Page 367 allHomework : NTG pages
63 In a graph of distance versus time, the slope represents DisplacementSpeedAccelerationPotential energy
64 True or falseMotion is measured relative to a reference point.
65 Average speed of the object Acceleration of the object When you know both the speed and direction of an object’s motion, you know theAverage speed of the objectAcceleration of the objectDistance the object has traveledVelocity of the object
66 True or falseA child riding on a merry-go-round is acceleration because his direction is changing.
67 CompletionThe distance traveled by a moving object per unit of time is called ___________.
68 CompletionA speed of 20 kilometers per hour is abbreviated as 20 ____________.
69 When an object’s distance from another object is changing, It is in motionIt is moving at a constant speedIt has high velocityIt is accelerating
71 The rate of which velocity changes is called Instantaneous speedDirectionAccelerationMotion
72 CompletionIf a car is speeding up, its initial speed is _______________ than its final speed.
73 The location of the object The acceleration of the object If you know the distance an object has traveled in a certain amount of time, you can determineThe size of he objectThe speed of the objectThe location of the objectThe acceleration of the object
74 CompletionA quantity that consists of both a magnitude and direction is called a(n) _________________.
75 If you are moving in a circle at a constant speed, are you accelerating? Justify your answer
