Question

question 16 (1 point)which of the following graphs depicts uniform motion?abcde○ a and b○ c and d○ a and c○ b and d○ e only

Explanation:

Uniform motion means constant velocity. For distance-time (d-t) graphs, this is a straight line (constant slope, since $v=\frac{\Delta d}{\Delta t}$). For velocity-time (v-t) graphs, this is a horizontal line (constant velocity, zero acceleration).

• Graph A: d-t graph, decreasing slope → decreasing speed, not uniform.
• Graph B: d-t graph, increasing slope → increasing speed, not uniform.
• Graph C: v-t graph, straight increasing line → constant acceleration, not uniform.
• Graph D: v-t graph, straight decreasing line → constant deceleration, not uniform.
• Graph E: v-t graph, horizontal line → constant velocity, uniform motion.

Answer:

E only
