identify and describe all points of acceleration in the following scenario. make sure to explain why each example is a point of acceleration.
a female bear leaves her bear cubs in their den to go out in search of food. she travels 1 mile in 30 minutes, heading east. she travels quickly at first, but then she becomes tired and begins moving more slowly. she finds no food, so she then heads north for another 10 minutes. she finds a river so she is able to catch a few fish for her bear cubs. she then turns around and heads back toward her den. she travels southwest and returns home to feed her cubs.

Explanation:

Acceleration is a change in velocity. Velocity has both speed and direction. When the bear starts quickly (change in speed - acceleration), then slows (change in speed - acceleration), then changes direction (north - acceleration), then turns around (change in direction - acceleration).

Answer:

1. When she starts quickly: Change in speed (acceleration).
2. When she becomes tired and slows: Change in speed (acceleration).
3. When she heads north: Change in direction (acceleration).
4. When she turns around: Change in direction (acceleration).
