Front

What is the difference between vector and scalar quantities?

Back

Vector quantities have both magnitude and direction, while scalar quantities have only magnitude.

Front

Is speed a vector or a scalar quantity?

Back

Speed is a scalar quantity because it only has magnitude and no direction.

Front

Is acceleration a vector or a scalar quantity?

Back

Acceleration is a vector quantity because it has both magnitude and direction.

Front

What does the term 'magnitude' refer to in physics?

Back

Magnitude refers to the size or amount of a quantity, regardless of its direction.

Front

What is an example of a scalar quantity related to volume?

Back

Volume is a scalar quantity because it only has magnitude and no direction.

Front

How would you classify the quantity '15 meters per second due west'?

Back

'15 meters per second due west' is a vector quantity because it includes both magnitude (15 m/s) and direction (due west).
