Question b
Which of the following are vector quantities and which are scalar quantities? time force mass velocity
Worked Solution & Example Answer:Which of the following are vector quantities and which are scalar quantities? time force mass velocity - Leaving Cert Physics - Question b - 2014
Step 1
Identify vector quantities
Answer
In physics, vector quantities have both magnitude and direction. Among the given options, force and velocity are vector quantities.
- Force: This is a vector since it describes both the strength and direction of an interaction.
- Velocity: This indicates both speed and direction of an object's motion.
Step 2
Identify scalar quantities
Answer
Scalar quantities only have magnitude and no direction. The following are scalar quantities from the options provided:
- Time: It is a measurement of duration and does not have a direction.
- Mass: This is a measure of the amount of matter in an object, expressed in kilograms, and also lacks direction.
