Velocity and Acceleration Put your Name Here

Moving Man Game Hit Chart: Screenshot the position graph Screenshot the Velocity graph Screenshot the acceleration graph 1. How many meters did you cover every second? 1.Why was the line a flat line… 2. Velocity has speed value and a __________, HINT: look at the arrow 1.Describe your acceleration line

Moving Man Game Hit Chart: Screenshot the position graph Screenshot the Velocity graph Screenshot the acceleration graph 1. How is you position graph different from the last slide 1.Describe what is happening to you velocity graph 2. How much is velocity increasing every second 1.What is the acceleration of your man? 2.How does positive acceleration affect your man

Moving Man Game Hit Chart: Screenshot the position graph Screenshot the Velocity graph Screenshot the acceleration graph 1. How is you position graph different from the last slide 1.What happen to your velocity 2. Describe what happens to your velocity direction 3 What happens to your graph when the man turns left 1.What is the acceleration of your man? 2.How does negative acceleration effect your man?

Velocity (Use page 44) 4 POINTS 1. How is speed and velocity different? 2. Explain how an object can change velocity but not change speed. Velocity Speed 32 m/s to the north 32 m/s 54 mph 32 m/s towards England Put these boxes in the correct column

Velocity 3. Define velocity? Provide a picture to represent a moment when knowing velocity is useful… label the picture

Acceleration ( page 47-48) 1. What is acceleration? 2. List the three ways that an object can acceleration 3. Provide the mathematical formula for acceleration? A= Velocity Final Velocity Initial minus Time Organize these in correct order Provide a picture that represents all three ways that an object accelerates Acceleration= 1. 2. 3. 1. 2. 3. Acceleration=

Acceleration Math 4. If an object goes from 0-50 mph in 10 seconds what is the acceleration? Velocity final= Velocity Initial= Time= 5. If an object goes from 20-0 mph in 5 seconds what is the acceleration? Velocity final= Velocity Initial= Time= Acceleration=

Negative/Positive Acceleration 6. Do speeding up objects have a positive acceleration or a negative acceleration? 7. Do slowing down objects have a negative or positive acceleration? Provide a Picture of an object has negative acceleration Provide a Picture of an object has positive acceleration

Speed Animations(4 pts) Direction of Acceleration and Velocity 1.Explain the direction of arrows for both acceleration and velocity when an object is - Speeding up: -Slowing down: -Changing direction:

Acceleration vs. Constant Velocity Acceleration vs Constant Velocity 1. Which car or cars (red, green, and/or blue) are undergoing an acceleration? Study each car individually in order to determine the answer. 2. Which car (red, green, or blue) experiences the greatest acceleration? 3. Consider the position-time graph at the right. Each one of the three lines on the position-time graph corresponds to the motion of one of the three cars. Match the appropriate line to the particular color of car. Example …..RED= B Answer Here Blue: Green: Red: Blue: Green: Red:
