Actually, it depends on how you define the coordinate axes, but usually when moving forward, negative acceleration decreasesspeed, positive acceleration increasesit.
Positive acceleration occurs when an object's velocity is increasing over time, while negative acceleration (or deceleration) happens when an object's velocity is decreasing over time. Positive acceleration can be due to speeding up, turning, or changing direction, while negative acceleration is typically caused by slowing down or stopping.
In this case, acceleration is positive. Negative acceleration would cause the object to slow down (decelerate.)
Retardation or deceleration is negative acceleration. It is opposite to the direction of velocity.
Yes, both velocity and acceleration can be negative. Negative velocity indicates movement in the opposite direction of a chosen positive direction, while negative acceleration indicates a decrease in velocity in the chosen positive direction.
You add them. For example, if a block is accelerating to the right at 2 m/s2 but is being slowed by friction accelerating the block to the left at 1 m/s2, then you can add the accelerations--positive is right and negative is left. The net acceleration would be 1 m/s2 to the right.
Yes, acceleration can be positive and negative because acceleration is a vector. It has both direction and magnitude. The direction is what makes it positive or negative. Negative acceleration is usually called deceleration.
Positive is speeding up and negative is slowing down
Positive acceleration = speeding up. Negative acceleration = slowing down.
Positive acceleration ==> speeding up Negative acceleration ==> slowing down

When a softball is thrown, it has a positive acceleration because its velocity is increasing with time as it moves through the air.
Yes, both velocity and acceleration can be negative. Negative velocity indicates movement in the opposite direction of a chosen positive direction, while negative acceleration indicates a decrease in velocity in the chosen positive direction.

positive acceleration is when things speed up; negative acceleration is when things slow down; and zero acceleration is when things do not speed up or slow down, this is called constant speed, or no change in velocity.
Acceleration is positive when an object is speeding up in the positive direction (e.g., increasing velocity), and negative when the object is slowing down in the positive direction or moving in the negative direction (e.g., decreasing velocity). The sign of acceleration depends on the direction of the change in velocity relative to the direction of motion.
