Vectors, Scalars, Distance and Displacement

Front

What is a scalar quantity?

Back

A quantity that has magnitude but no direction.

Front

What is a vector quantity?

Back

A quantity that has both magnitude and direction.

Front

Which of the following is a scalar: distance, velocity, or acceleration?

Back

Distance is a scalar quantity.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the shortest straight-line distance from the initial to the final position.

Front

If a person walks 3 km east and then 4 km north, what is their displacement?

Back

5 km northeast (using the Pythagorean theorem).

Front

What is the formula for calculating displacement?

Back

Displacement = final position - initial position.

Front

If Liza swims 4 laps in a 50 meter pool, what is her total distance?

Back

200 meters (4 laps x 50 meters).

Front

If Liza swims 4 laps in a 50 meter pool, what is her displacement?

Back

0 meters (she ends up where she started).

Front

What is the unit of measurement for vectors?

Back

Vectors can be measured in units such as meters, kilometers, etc., depending on the context.

Front

What does it mean for a vector to have a direction?

Back

It indicates the line along which the vector acts, such as north, south, east, or west.
