Vectors, Scalars, Distance and Displacement - SFHS K Wood

Front

What is a vector?

Back

A quantity that has both magnitude and direction.

Front

What is a scalar?

Back

A quantity that has only magnitude and no direction.

Front

What is the difference between distance and displacement?

Back

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

Front

If Jerry walked 2 km to school and then 6 km to the park, what is his total distance?

Back

8 km

Front

What is the displacement if a person walks 3 meters east and then 4 meters west?

Back

1 meter west.

Front

How do you calculate the resultant vector of two perpendicular vectors?

Back

Use the Pythagorean theorem: Resultant = √(A² + B²) where A and B are the magnitudes of the vectors.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

If a car travels 60 km in 1 hour, what is its speed?

Back

60 km/h.

Front

What is the significance of direction in vector quantities?

Back

Direction is essential in vector quantities as it determines the vector's orientation in space.

Front

If a person runs 5 km north and then 5 km south, what is their displacement?

Back

0 km.
