Question

whats the speed at a particular moment in time called? answer options: select one of four variable speed instantaneous speed uniform speed constant speed

Explanation:

To determine the correct answer, we analyze each option:

• Variable speed: Speed that changes over time, not at a particular moment.
• Instantaneous speed: Defined as the speed of an object at a specific (particular) moment in time.
• Uniform speed: Speed that remains constant over a period, not a specific moment.
• Constant speed: Same as uniform speed, constant throughout, not a moment-specific speed.

So, the speed at a particular moment in time is called instantaneous speed.

Answer:

B. Instantaneous speed (assuming the options are labeled A: Variable speed, B: Instantaneous speed, C: Uniform speed, D: Constant speed; if labels differ, adjust to match the correct option text "Instantaneous speed" with its identifier)
