Negative acceleration, also known as deceleration, is a decrease in the rate of change of an object's velocity. This means that the object is either slowing down or changing direction in a way that causes its speed to decrease.
Negative acceleration is measured in units of distance per time squared, such as meters per second squared (m/s^2) in the metric system. This measurement indicates how much the velocity of an object changes in a certain amount of time due to negative acceleration.
Negative acceleration can be caused by various factors, such as friction, air resistance, or the force of gravity. These forces act in the opposite direction of an object's motion, causing it to slow down or change direction.
Negative acceleration and positive acceleration are opposites. While negative acceleration causes an object to slow down or change direction, positive acceleration causes an object to speed up or maintain a constant velocity in the direction of motion.
Yes, negative acceleration can be beneficial in some cases. For example, when a car is approaching a stop sign, the driver must apply the brakes to apply negative acceleration and slow down the car. This helps to avoid collisions and maintain control of the vehicle.
