Analysis of Specific Situations

Where is the object at rest? Where the velocity is zero. 7 6 8 (b) 1 time 9 (c) 2 10 (a) 5 3 4 Where is the object at rest? Where the velocity is zero.

Where is the speed constant? Where the graph is horiz. and ≠ 0 Velocity 7 6 8 (b) 1 time 9 (c) 2 10 (a) 5 3 4 Where is the speed constant? Where the graph is horiz. and ≠ 0

Where is the speed greatest? Where the magnitude of the speed Velocity 7 6 8 (b) 1 time 9 (c) 2 10 (a) 5 3 4 Where is the speed greatest? Where the magnitude of the speed is the greatest.

Where is the object moving away? Where the graphs are above, ≠ 0. Velocity 7 6 8 (b) 1 time 9 (c) 2 10 (a) 5 3 4 Where is the object moving away? Where the graphs are above, ≠ 0.

Where is the object moving toward? Where the graphs are below, ≠ 0. Velocity 7 6 8 (b) 1 time 9 (c) 2 10 (a) 5 3 4 Where is the object moving toward? Where the graphs are below, ≠ 0.

Where is the acceleration positive? Where the slope is positive. Velocity 7 6 8 (b) 1 time 9 (c) 2 10 (a) 5 3 4 Where is the acceleration positive? Where the slope is positive.
