Question

mission kg7: interpreting velocity-time graphs
the motion of six objects - a, b, c, d, e, and f - are represented by lines on a velocity-time graph. write the letter(s) for any object that has a constant, negative acceleration (during the entire motion). if there are no instances of a constant, negative acceleration, then tap on the no answer button.

Explanation:

In a velocity-time graph, acceleration is the slope of the line. A constant negative acceleration means a straight line with a negative (downward from left to right) slope, maintained for the entire motion.

• Object A: Positive slope (positive acceleration)
• Object B: Zero slope (zero acceleration)
• Object C: Zero slope (zero acceleration)
• Object D: Positive slope (positive acceleration)
• Object E: Zero slope (zero acceleration)
• Object F: Negative slope (constant negative acceleration)

Answer:

F
