Question

drag and drop the following formulas and examples to classify them as pertaining to acceleration, speed, or velocity.
acceleration
speed
velocity
=d/t in a specific direction
=d/t
=δv/t
30 m/s²
30 m/s
30 m/s north

Explanation:

Step1: Recall definitions

Acceleration is the rate of change of velocity, formula \(a = \frac{\Delta V}{T}\), and has units like \(m/s^{2}\). Speed is the rate of change of distance, formula \(s=\frac{D}{T}\), and has units like \(m/s\). Velocity is speed in a specific direction, formula \(v=\frac{D}{T}\) (with direction), units like \(m/s\) (with direction).

Step2: Classify each item

• \(=\frac{\Delta V}{T}\) and \(30 m/s^{2}\) belong to Acceleration.
• \(=\frac{D}{T}\) and \(30 m/s\) belong to Speed.
• \(=\frac{D}{T}\) in a specific direction and \(30 m/s\) north belong to Velocity.

Answer:

Acceleration: \(=\frac{\Delta V}{T}\), \(30 m/s^{2}\)
Speed: \(=\frac{D}{T}\), \(30 m/s\)
Velocity: \(=\frac{D}{T}\) in a specific direction, \(30 m/s\) north
