Speed and Velocity Flashcard

Front

What is speed?

Back

Speed is the distance traveled per unit of time, calculated as Distance/Time.

Front

What is the formula for calculating speed?

Back

S = D/T, where S is speed, D is distance, and T is time.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

How does velocity differ from speed?

Back

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

Front

What is distance?

Back

Distance is the total length that needs to be traveled from one point to another.

Front

What is displacement?

Back

Displacement is the shortest path between two points, considering direction.

Front

What units are commonly used to measure speed?

Back

Common units for speed include meters per second (m/s) and kilometers per hour (km/h).

Front

If a car travels 100 meters in 5 seconds, what is its speed?

Back

Speed = Distance/Time = 100 m / 5 s = 20 m/s.

Front

What does a speed-time graph represent?

Back

A speed-time graph shows how speed changes over time.

Front

What is the significance of a flat line on a speed-time graph?

Back

A flat line indicates that the object is moving at a constant speed.
