Classify the following as scalars and vector quantities:
i. Time period
ii. Distance
iii. Displacement
iv. Force
v. Work
vi. Velocity
vii. Acceleration
i. Time period - is a scalar quantity as it involves only magnitude. A scalar quantity is a one - dimensional measurement of a quantity. Eg: 10 seconds has only magnitude, i.e., 10 and no direction.
ii. Distance - is a scalar quantity as it involves only magnitude. A scalar quantity is a one dimensional measurement of a quantity. Eg: 5meters has only magnitude 5 and no direction.
iii. Displacement - is vector quantity as it involves both magnitude and direction. Vector quantity has both magnitude and direction.
iv. Force - is a vector quantity as it involves both magnitude and direction. Vector quantity has both magnitude and direction. Eg., 5N downward has magnitude of 5 and direction is downward.
v. Work done - is a scalar quantity as it involves only magnitude and no particular direction. A scalar quantity is a one dimensional measurement of a quantity.
vi. Velocity - is a vector quantity as it involves both magnitude as well as direction. Vector quantity has both magnitude and direction. Eg., 5m/s east has magnitude of 5m/s and also direction towards east.
vii. Acceleration is a vector quantity because it involves both magnitude as well as direction.
