Displacement, Distance, Speed, Velocity

Front

What is displacement?

Back

Displacement is a vector quantity that refers to the change in position of an object. It is the shortest distance from the initial to the final position, along with the direction.

Front

What is distance?

Back

Distance is a scalar quantity that represents the total length of the path traveled by an object, regardless of direction.

Front

What is speed?

Back

Speed is a scalar quantity that measures how fast an object is moving, calculated as the distance traveled divided by the time taken.

Front

What is velocity?

Back

Velocity is a vector quantity that refers to the rate at which an object changes its position, calculated as displacement divided by the time taken.

Front

Which of the following is a vector: Displacement, Distance, Speed?

Back

Displacement is a vector.

Front

If Jermaine runs 2 laps around a 400 meter track in 58.6 seconds, what is his average velocity?

Back

0 m/s (since he returns to the starting point, the displacement is zero).

Front

Scott travels north 5 miles, west 3 miles, and then east 6 miles. What is the magnitude of his displacement?

Back

5.83 miles.

Front

How do you calculate average velocity?

Back

Average velocity is calculated by dividing the total displacement by the total time taken.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is the formula for calculating displacement in a straight line?

Back

Displacement = Final Position - Initial Position.
