Constant Speed
This would indicate negative acceleration, which would mean that the object in question is speeding up.
Force greater than gravity
it is functions that goes all around you and body
Take the component of the acceleration along the direction the object is moving. If this component is positive (the acceleration vector, or the relevant component, points in the same direction as the movement), then the object is speeding up.
don't know, only three though

When it is stationary, or when the velocity is constant. If it is speeding up or slowing down, it has acceleration.

The direction of angular acceleration comes from whether the angular speed of the object is clockwise or counterclockwise and whether it is speeding up or slowing down.The direction of the angular acceleration will be positive if the angular velocity is counterclockwise and the object's rotation is speeding up or if the angular velocity is clockwise and the object's rotation is slowing downThe direction of the angular acceleration will be negative if the angular velocity is clockwise and the object's rotation is speeding up or if the angular velocity is counterclockwise and the object's rotation is slowing downThe angular acceleration will not have a direction if the object's angular velocity is constant
yes the acceleration can take a negative value. for example an object with an accleration of -2 ms-2 would be slowing down. However this is normally called deceleration.
Yes, it can move in a curve.
a. the object is turning b. the object is not moving c. the object is speeding up d. the object is slowing down e. this situation would not be physically possible
It means the object is decelerating - slowing down rather than speeding up. You can think of it as negative acceleration.
If the object is not moving, or is traveling at a constant velocity, all forces acting on the object are equal and opposite to each other. If the object is accelerating (speeding up, slowing down, or changing direction) the forces are not balanced.
