Question

Check all of the following that are scalar quantities.

a. speed
b. velocity
c. displacement
d. distance
e. time

Answer 1

The scalar quantities in physics are speed, distance, and time.

Step-by-step explanation:

The scalar quantities are:

• Speed: Speed is a scalar quantity because it only indicates the magnitude of how fast an object is moving and does not require a direction. For example, if a car is traveling at 60 mph, the speed is 60 mph.
• Distance: Distance is a scalar quantity because it only represents the magnitude of the length between two points and does not involve any direction. For example, if a person travels 10 meters, the distance traveled is 10 meters.
• Time: Time is a scalar quantity because it is measured in terms of magnitude only and does not involve any direction. For example, if an event lasts for 2 hours, the time duration is 2 hours.
