Question

Where Are You Going ? Select the statement that describes the speed and velocity of two tennis players when one walks away to the southwest and the other to the northeast , with both walking at the same pace

Answer 1

Answer:

Speed: a tennis player moving at 3 m/s

Velocity: a tennis player moving at 3 m/s in the northeast direction

Explanation:

Here the statements are not given, however we can explain the difference between speed and velocity and give two examples.

• Speed is a scalar quantity which tells how fast an object is moving, regardless of its direction. It is calculated as distance covered divided by time taken.
• Velocity is a vector quantity, which has a magnitude and a direction. The magnitude is the ratio between the displacement (a vector connecting the initial position to the final position) and the time taken, while the direction goes from the initial position to the final position.

Therefore, examples of speed and velocity are:

Speed: a tennis player moving at 3 m/s

Velocity: a tennis player moving at 3 m/s in the northeast direction (for velocity, direction must also be specified)
