What is positive and negative acceleration?
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.
Acceleration is the rate at which happens?
Acceleration is the rate at which an object's velocity changes over time. It is measured in meters per second squared (m/s^2) and can be positive, negative, or zero depending on the direction and magnitude of the velocity change.
When velocity is zero and acceleration is negative what happens to the object in motion?
If velocity is zero and acceleration is negative, the object will start moving in the direction opposite to its previous motion. It will decelerate and eventually come to a stop before moving in the opposite direction.
When you press your bicycle's brakeswhat happens to your speedvelocityand acceleration?
your seed,velocity,and acceleration will be slow When you brake, your acceleration increases (!), your velocity decreases (and in this case, there is no difference between velocity and speed). Negative acceleration increases when braking a moving bike.
When velocity is zero and acceleration is negative what happens to an object's motion?
When velocity is zero and acceleration is negative, the object may be coming to a stop and starting to move in the opposite direction. The negative acceleration is causing the object to slow down, while the zero velocity indicates that it has momentarily come to a halt before changing direction.
What is positive and negative acceleration?

Positive acceleration can be due to speeding up, turning, or changing direction, while negative acceleration is typically caused by slowing down or stopping.
When velocity is negative and acceleration is positive what happens to an objects motion?
Its slowing down (but still moving).
Acceleration is the rate at which happens?
Acceleration is the rate at which an object's velocity changes over time. It is measured in meters per second squared (m/s^2) and can be positive, negative, or zero depending on the direction and magnitude of the velocity change.

If velocity is zero and acceleration is negative, the object will start moving in the direction opposite to its previous motion. It will decelerate and eventually come to a stop before moving in the opposite direction.

How can an object slowing down have an acceleration that's not negative?
If the positive direction was defined at the outset as the direction opposite to the direction in which the object happens to be moving just now, and the object is slowing down, then the acceleration is positive because, algebraically, the object's speed is increasing in the positive direction.
When velocity is positive and acceleration is zero what happens to an objects motion?
When acceleration is zero, then the object is moving in a straight line with constant speed. (That's the effective meaning of constant velocity.)
When velocity is zero and acceleration is negative what happens to an object's motion?
When velocity is zero and acceleration is negative, the object may be coming to a stop and starting to move in the opposite direction. The negative acceleration is causing the object to slow down, while the zero velocity indicates that it has momentarily come to a halt before changing direction.
Two words for what happens when an objects velocity decreases?
negative acceleration
What happens to a velocity when the acceleration changes?
If the acceleration changes, the velocity of an object will also change. If the acceleration increases, the velocity will increase. If the acceleration decreases, the velocity will decrease. The velocity and acceleration of an object are directly related.
What happens when you put a negative acceleration and positive acceleration together?
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.
What happens to the velocity if acceleration is zero?
The velocity stays the same, it is constant
