Play->Next->Click the button “Slope Off” change to “Slope On”
7. Using the position versus time graphs or the displacement versus time graphs, find the values listed below. Data set 1 above a graph is for mass 1 and data set 2 above a graph is for mass 2. Remember, you can use the computer to quickly find slopes. v1i = v1f = Δv1 = Δp1 = v2i = v2f = Δv2 = Δp2 = How do the changes in velocities compare for the two objects?
How do the impulses compare for the two objects?
8. Using the velocity versus time graph, find the values listed below. Remember, you can use the computer to quickly find slopes. a1 = F1 = a2 = F2 = How do the accelerations compare for the two objects?
How do the forces compare for the two objects?
Which object, the larger or smaller, has the greater absolute acceleration?
9. Using the momentum versus time graph, find the values listed below. Remember, you can use the computer to quickly find slopes. F1 = a1 = F2 = a2 = Is the total momentum conserved?
