Question

How can acceleration be negative?

Answer 1

Negative acceleration:

1. Acceleration is defined as the rate of change of velocity with respect to time.
2. Negative acceleration is defined as the acceleration in the defined “negative” direction.
3. So, negative acceleration means acceleration in the negative direction of the reference frame.
4. Negative acceleration decreases the velocity or speed of an object in motion depending upon the direction of the object's motion.
5. Negative acceleration is also termed as retardation.
6. A ball thrown upward will reach a certain height due to constant negative acceleration.
7. A car traveling in a specific direction will come to rest after applying its breaks due to negative acceleration.
