Question

How do positive and negative acceleration differ?

1. positive acceleration represents an object speeding up; negative acceleration represents an object slowing down

2. positive acceleration moves North or east; negative acceleration moves south or west

3. positive acceleration occurs when there is more velocity than speed; negative acceleration occurs when there is less velocity than speed.

4. positive acceleration occurs when an object changes its speed but not its direction; negative acceleration occurs when an object changes both its speed and direction​

Answer 1

1. positive acceleration represents an object speeding up; negative acceleration represents an object slowing down

Step-by-step explanation:

Acceleration is clearly defined as the rate of change of velocity with time. When are body is speeding up as we say, it is accelerating. When a body is coming to rest, it is decelerating.

Positive acceleration occurs when the speed of a moving continues to increase.

Negative acceleration is when the speed of a moving body reduces drastically.
