3. What is the difference between positive and negative acceleration?
Question
- What is the difference between positive and negative acceleration?
Solution
Positive and negative acceleration refer to the increase and decrease in velocity of an object over time, respectively.
-
Positive Acceleration: This occurs when an object's velocity increases over time. If you're driving a car and you press the gas pedal, your speed will increase. This is positive acceleration. The object is speeding up.
-
Negative Acceleration (also known as deceleration): This occurs when an object's velocity decreases over time. If you're driving that same car and you press the brake pedal, your speed will decrease. This is negative acceleration. The object is slowing down.
The direction of acceleration depends on two factors: whether the object is speeding up or slowing down, and whether the object is moving in the positive or negative direction. For example, if an object is moving in the positive direction and slowing down, it has negative acceleration. If an object is moving in the negative direction and speeding up, it also has negative acceleration.
