Distance vs. Displacement

Front

What is the definition of displacement?

Back

Displacement is the change in an object's position from its initial position to its final position, taking into account the direction.

Front

How is displacement different from distance?

Back

Distance is a scalar quantity that refers to the total path length traveled by an object, while displacement is a vector quantity that refers to the shortest straight-line distance from the initial to the final position, including direction.

Front

If a skier moves 10 meters east, 14 meters west, and then 6 meters east, what is their total displacement?

Back

The total displacement is 2 meters east.

Front

What is the total displacement of Jerry who walked from home to school and then to the park, ending up 2 km east of his starting point?

Back

Jerry's total displacement is 2 km east.

Front

A person walks 50 meters north and then 32 meters south. What is their displacement?

Back

The displacement is 18 meters north.

Front

If Bill runs 400 meters to Andy's house and then back home, what is his displacement?

Back

Bill's displacement is 0 meters.

Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has magnitude only and no direction, such as distance.

Front

What is a vector quantity?

Back

A vector quantity is a physical quantity that has both magnitude and direction, such as displacement.

Front

How do you calculate displacement when given multiple movements in different directions?

Back

To calculate displacement, sum the individual displacements considering their directions, treating opposite directions as negative.

Front

What is the significance of direction in displacement?

Back

Direction is crucial in displacement because it determines the overall change in position and distinguishes it from distance.
