Question

multiple - choice question
a car going from 60mph to 80mph is not an example of acceleration because its direction wasnt mentioned
true
false

Explanation:

Step1: Recall the definition of acceleration

Acceleration is the rate of change of velocity. Velocity is a vector quantity (has both magnitude and direction), but speed is a scalar quantity (only magnitude). If a car's speed changes (from 60 mph to 80 mph), even if direction is not mentioned, there is a change in the magnitude of velocity (assuming motion in a straight - line path where speed is related to the magnitude of velocity).

Step2: Analyze the statement

The statement claims that "A car going from 60mph to 80mph is NOT an example of acceleration because its direction wasn't mentioned". But acceleration can be due to a change in the magnitude of velocity (speed change in case of straight - line motion) or a change in direction or both.

Answer:

False
