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 is a scalar quantity representing how fast an object is moving, which is shown by the 30 m/s value. Velocity is a vector (needs direction), and since the description just says "up, down, and around" without a specific direction for velocity (like a constant direction for velocity), it's not velocity. Acceleration is a change in velocity (could be speed change or direction change). Here, moving “up, down, and around” implies a change in direction (so change in velocity, thus acceleration).

Answer:

speed, acceleration
