Question

complete the sentences to describe the difference between speed and velocity. speed describes how fast an object moves. speed is described by and time. velocity is speed with. velocity is described by and time.

Explanation:

1. Recall the formula for speed: \( \text{Speed} = \frac{\text{Distance}}{\text{Time}} \), so speed is described by distance and time.
2. Velocity is a vector quantity, meaning it has both magnitude (speed) and direction. So velocity is speed with direction.
3. The formula for velocity (in terms of displacement) is \( \text{Velocity} = \frac{\text{Displacement}}{\text{Time}} \), so velocity is described by displacement and time.

Answer:

• The first blank: distance
• The second blank: direction
• The third blank: displacement
