Question

bert is traveling at 30 m/s up, down, and around. is this an example of speed, velocity, or acceleration? (check all that apply) velocity speed acceleration

Explanation:

• Speed: It is a scalar quantity representing how fast an object is moving. Here, \(30\ m/s\) is the magnitude of the rate of motion, so speed applies.
• Velocity: Velocity is a vector quantity (has both magnitude and direction). Since the problem mentions "up, down, and around" (direction - changing), we cannot define a single - valued velocity (as velocity requires a specific direction at a given instant, and here the overall description is too vague for a single velocity value in the context of the question's simplicity), so velocity does not apply.
• Acceleration: Acceleration is the rate of change of velocity. If an object is moving "up, down, and around", its direction of motion (and thus velocity) is changing. A change in velocity (either in magnitude or direction) implies acceleration.

Answer:

speed, acceleration
