703 Flashcard: Labels, Vectors, and Scalars

Front

What is a vector?

Back

A vector is a quantity that has both magnitude and direction, such as velocity or displacement.

Front

What is a scalar?

Back

A scalar is a quantity that has only magnitude and no direction, such as mass or temperature.

Front

What does 'm' stand for in units?

Back

The letter 'm' is the abbreviation for meters.

Front

What does 'm/s' stand for in units?

Back

The abbreviation 'm/s' stands for meters per second, a unit of speed.

Front

Is 13.6 mi east a scalar or vector?

Back

13.6 mi east is a vector because it has both magnitude (13.6 miles) and direction (east).

Front

Is 120 kg a scalar or vector?

Back

120 kg is a scalar because it has only magnitude (120 kilograms) and no direction.

Front

Is 22 m/s^2 west a scalar or vector?

Back

22 m/s^2 west is a vector because it has both magnitude (22 m/s^2) and direction (west).

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 unit of force in the International System of Units (SI)?

Back

The unit of force in SI is the Newton (N), which is equivalent to kg·m/s².

Front

What is displacement?

Back

Displacement is a vector quantity that refers to the change in position of an object, measured as the shortest distance from the initial to the final position.
