Unit 3 Exam

For you exam know: Key Terms: Acceleration, Origin Analyzing x-t graphs for accelerated objects (be

able to state starting position, direction of motion, direction of slope)

Analyzing v-t graphs for accelerated objects (be able to write whether object constant, speeding up or slowing down)

Analyzing slope to find direction of acceleration Creating x-t, v-t, and a-t graphs Calculating average speed from slope Creating average speed v-t graph Finding displacement from area under curve
