Question a
Give an example of (i) a vector quantity, (ii) a scalar quantity.
Worked Solution & Example Answer:Give an example of (i) a vector quantity, (ii) a scalar quantity. - Leaving Cert Physics - Question a - 2013
Step 1
(i) a vector quantity
Answer
An example of a vector quantity is displacement. Displacement is defined as the shortest distance from the initial to the final position of an object, accompanied by a specified direction. For instance, if a person walks 5 meters to the north, their displacement is 5 meters north.
Step 2
(ii) a scalar quantity
Answer
An example of a scalar quantity is temperature. Temperature measures the degree of heat present in a substance and does not include a direction. For example, a temperature reading of 25 degrees Celsius simply conveys a state of heat without any directional information.
