Homework Handout #2 Name, Class Period, Add title “Homework Handout #2” For each section of the given graphs, indicate: - direction (positive, negative, stopped) - type of motion (constant or non-constant vel) - if constant rate of motion (high, middle, low) - if NC, is object getting faster or slower
For the following graphs: Copy down to your paper Divide the motion up into sections –Each section should only have one type of motion Indicate: direction, velocity type, rate of motion or how the velocity changes
Questions What do the vertical numbers represent? What does a horizontal line represent on this graph? What does a sloping line represent on this graph?
For each section of the P-T graph, determine: a.Direction of motion b.Constant velocity or constant acceleration c.If accelerating, is object getting faster or slower
For each section of the V-T graph, determine: a. Direction of motion b. Constant velocity or constant acceleration c. If accelerating, is object getting faster or slower
For each velocity-time graph, draw the equivalent position time graph
Do Now Describe the motion that produced the following V-T graph: V (m/s) -5 4 510 13 20 24 30 t (s)
Assignment based on walking in front of motion detector Some need to get the graph Once graph is in your possession –Divide up into section, with only one type of motion for each section, describe motion –Identify one section with constant velocity, calculate by using slope off P-T graph –Identify one section with constant acceleration, calculate by using the slope off V-T graph –Find the overall velocity
For this graph, what are the overall: Displacement Distance Velocity
Problem #5 Describe the motion in the following V-T graph. Then find the overall velocity of the first 2 sections -18 m/s 8s 11s
Given the following Velocity-Time graph, indicate the type of motion in each section. Include information on direction, acceleration or constant velocity
Find the overall velocity for the first 2 sections in the V-T graph
Example Q. #3 A) Draw a P-T graph that shows an object remaining at rest for 15 seconds B) Draw a V-T graph that shows an object speeding up backwards at a uniform acceleration for 15 seconds
What to do for each graph: For each section with the same type of motion, you should be able to determine: –Is the object moving positive, negative, or stopped –Is the motion constant or not? –If constant, is the rate of motion fast, average or slow? –If not constant, is the object getting faster or slower?
