negative acceleration means that the object is accelerating in a negative direction.
For instance, if an object is going at a certain velocity forward, but accelerating negatively, it would slow down and eventually start moving backwards. It's a bit of a strange concept, but I hope this helps
At that moment, the object isn't moving - but since the velocity is changing, it soon will.
Retardation or negative acceleration or deceleration.
Acceleration is negative when the object is moving in the opposite direction. on a graph the line would be in the negative quadrant.
No. A negative acceleration could mean a change in direction
Observe that the object below moves in the negativedirection with a changing velocity. An object which moves in the negative direction has a negative velocity. If the object is speeding up then its acceleration vector is directed in the same direction as its motion (in this case, a negative acceleration).
If the mass of an object increases, what happens to the acceleration?
At that moment, the object isn't moving - but since the velocity is changing, it soon will.
its acceleration will be increased
The acceleration of the object increases.
its acceleration will be increased
Retardation or negative acceleration or deceleration.
Negative
Retardation or negative acceleration or deceleration.
Acceleration is negative when the object is moving in the opposite direction. on a graph the line would be in the negative quadrant.
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.
No. A negative acceleration could mean a change in direction
Observe that the object below moves in the negativedirection with a changing velocity. An object which moves in the negative direction has a negative velocity.
