Question

Determine whether each phrase describes speed or velocity. The displacement of an object during a specific unit of time: How fast or slow an object is moving and in what direction: How fast or slow an object is moving: A cheetah running 97 km/h: A train traveling 45 m/s north:

Answer 1

The displacement of an object during a specific unit of time:  Velocity (the direction is part of displacement.)

How fast or slow an object is moving and in what direction: Velocity (speed & direction)

How fast or slow an object is moving:  Speed (no direction)

A cheetah running 97 km/h:  Speed (no direction)

A train traveling 45 m/s north:  Velocity (speed & direction)

Answer 2

Statement 1 and 2 show the speed.While the statement 3 shows the velocity.

What is a vector?

A vector is a quantity or phenomena with magnitude and direction that are independent of one another. The phrase also refers to a quantity's mathematical or geometrical representation.

Velocity is a vector quantity. While speed is a scalar quantity.

1. How fast or slow an object is moving shows speed.

2. A cheetah running 97 km/h shows speed because there is no direction.

3. A train traveling 45 m/s north referred to the velocity.Because it shows direction.

Hence, statements 1 and 2 show the speed. While the statement 3 shows the velocity.
