An example of a scalar is and an example of a vector is question options: velocity; displacement speed; velocity velocity; acceleration distance; speed

An example of scalar quantity is speed and an example of vector quantity is velocity.

A scalar quantity is a physical quantity that only has a magnitude(just a numerical value) but doesn't have any other characteristic like direction.

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

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
