Question

the three vehicles shown below are all traveling at a speed of 15 m/s, but only the pickup tru has a changing velocity. the pickup truck has a change in because the pickup truck is traveling on

Explanation:

To solve this, we analyze the concepts of speed and velocity:

Step 1: Recall the difference between speed and velocity

Speed is a scalar (magnitude only), while velocity is a vector (magnitude + direction). A change in velocity occurs if either speed or direction changes.

Step 2: Analyze the pickup truck’s motion

The pickup truck is moving on a curved path. Even if its speed (15 m/s) remains constant, its direction of motion is changing (since it’s on a curve). Since velocity depends on direction, a change in direction means a change in velocity.

Velocity is a vector (includes direction). The pickup truck travels on a curve, so its direction changes (even with constant speed), causing a change in velocity. The first blank is "velocity" (or "direction", but contextually, the change is in velocity due to direction change), and the second blank relates to the curved path (e.g., "a curve" or "a curved path").

Answer:

The pickup truck has a change in \(\boldsymbol{\text{velocity}}\) because the pickup truck is traveling on \(\boldsymbol{\text{a curved path}}\) (or "a curve"). (Note: The first blank focuses on the vector quantity changing, the second on the path causing direction change.)
