How does the direction of the acceleration along determine if the object is speeding up or slowing down?
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.
When does something accelerate in the direction opposite to its direction of motion?
If the object is speeding up, the acceleration is in the directionary of the velocity.
What is the definition of negative velocity?
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).
How do unbalanced forces affect an objects motion?
forces push and pull on an object making the object move in the direction of the force. the stronger force would overcome the lesser force, causing the object's motion to go in the direction of the stronger force (newton's 2nd law).alsoif forces are balanced there s no acceleration hence there is no motion.....thus if forces are unbalanced the motion is in the same direction as the resultant force (the greater force acting on an object)When the forces acting on an object are unbalanced, The one with more mass will pull on the other one, causing a change in motion.
How can an object be accelerating if it's slowing down?
Acceleration doesn't mean "speeding up". It only means that the speed or direction of motion, or both, are changing. Speeding up is positive acceleration in the direction you're moving. Slowing down is negative acceleration in the direction you're moving, or positive acceleration in the opposite direction.

What affect does earths gravity have upon a object entering earth?
In general, it will have the effect of speeding such an object up.

Acceleration doesn't mean "speeding up". It only means that the speed or direction of motion, or both, are changing. Speeding up is positive acceleration in the direction you're moving. Slowing down is negative acceleration in the direction you're moving, or positive acceleration in the opposite direction.
When a falling object stops speeding up and falls at a constant rate of speed that object has reached its?
terminal speed
What are the conditions for an object to stay at restto keep moving at constant velocity or to move with the increasing velocity?
If the sum of all forces on an object is zero, then the object remains in constant, uniform motion. 'Constant uniform motion' means motion in a straight line at a constant speed. The physical description of such motion is "constant velocity". "Rest" is just constant velocity with a speed of zero. If the sum of all forces on an object is NOT zero, then the object's velocity must change. The change may consist of speeding up, slowing down, or turning in a different direction.
