T3.2 Speed Flashcard

Front

What is the definition of velocity?

Back

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

Front

How does distance relate to time in a speed graph?

Back

Distance increases as time increases.

Front

What is the SI unit for measuring speed?

Back

Meters per second (m/s).

Front

If a snail travels 10 inches in 5 seconds, what is its speed?

Back

2 inches per second (in/s).

Front

What does the formula s = d/t represent?

Back

The formula represents speed, where 's' is speed, 'd' is distance, and 't' is time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the formula to calculate speed?

Back

Speed = Distance / Time.

Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has magnitude only and no direction.

Front

What is a vector quantity?

Back

A vector quantity is a physical quantity that has both magnitude and direction.

Front

How can you convert speed from inches per second to meters per second?

Back

To convert inches per second to meters per second, multiply by 0.0254 (since 1 inch = 0.0254 meters).
