Question

homework: use the dot diagrams to describe the motion of each object. object description of motion a b c d e

Explanation:

In a dot - diagram, equal spacing between dots over equal time intervals indicates constant velocity. Increasing spacing indicates acceleration and decreasing spacing indicates deceleration.

• Object A: Dots are evenly spaced, so it has a constant velocity.
• Object B: Dots are evenly spaced but with larger intervals than A, so it has a higher constant velocity than A.
• Object C: Spacing between dots is increasing, so it is accelerating.
• Object D: Spacing between dots is decreasing, so it is decelerating.
• Object E: First, dots are evenly spaced (constant velocity), then the spacing increases (acceleration).

Answer:

Object A: Constant velocity
Object B: Higher constant velocity
Object C: Acceleration
Object D: Deceleration
Object E: Constant velocity followed by acceleration
