Speed and Motion Flashcard 2

Front

What is displacement?

Back

The difference between an object's final position and its starting position.

Front

What is distance?

Back

How far an object travels.

Front

Does speed depend on direction?

Back

No.

Front

What is speed?

Back

The rate at which an object is moving.

Front

If Joe rides from point A to B to C, and the total distance is 12 m, what is the displacement if he ends at point C 5 m away from point A?

Back

5 m.

Front

If Joe rides 3 m from A to B and then 4 m from B to C, what is the total distance traveled?

Back

7 m.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

If an object travels 20 m in 4 seconds, what is its speed?

Back

5 m/s.

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

If a car moves east at 60 km/h, what is its velocity?

Back

60 km/h east.
