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).
Do Both speed and acceleration include the direction of an object's motion?
No. The velocity of an object is how fast it is moving as well as the direction of the motion. So when considering one dimension, the velocity can be positive or negative. The speed of the object is simply the magnitude (absolute value, in the case of one dimension) of the velocity, with no direction. Acceleration is the change in velocity and does include direction. So if an object has a positive velocity (in one dimension) and its speed increases, the acceleration is negative. However, if the speed of an object moving the negative direction increases, then the acceleration is negative, because the velocity becomes "more negative."
When velocity is zero and acceleration is negative what happens to an object's motion?
At that moment, the object isn't moving - but since the velocity is changing, it soon will.
What is negative acceleration?
Negative Acceleration:Negative Acceleration refers to an object whose speed decreases as it moves away from its original starting position.Actually, that's not entirely correct. Acceleration is a vector quantity and, therefore, depends on direction. If an object is moving in a straight line, in the negative direction, its acceleration is positive if its speed decreases with time and negative if its speed increases with time.Think of it this way: if the acceleration vector is pointed in the same direction as the way an object is moving, the object speeds up. If the acceleration vector is pointed opposite the direction of motion, it slows down.
What does it mean if an object is in motion?
acceleration

How does a negative or positive acceleration affect motion?
It can change the direction of motion or it can speed up or slow down an object.

How do unbalanced forces acting on an object its motion?
Balanced forces do not change its motion (no acceleration). Unbalanced forces changes the motion of the object (acceleration).
When an object slows down it's accelerate is?
When an object slows down, its acceleration is negative (in a linear sense), or in a direction opposed to its motion (in a vector sense).
How do balanced forces acting on an object affect its motion. How do unbalanced forces acting on an object affect its motion?
Balanced forces do not change its motion (no acceleration). Unbalanced forces changes the motion of the object (acceleration).
What does it mean if an object is in motion?
acceleration
How is motion and acceleration alike And how are they different?
Motion is the measurement of an object and the change of its position over time. Acceleration is the measurement of velocity of an object. Both terms are used in physics. Acceleration denotes an increase of speed of an object while motion does not.
A force that acts on an object does only when the object moves?
A force will produce acceleration when the object moves. force in the line of motion will increase the acceleration and the force opposite to the line of motion will decrease the acceleration.
How do unbalanced forces acting on an object affects it's motions?
Balanced forces do not change its motion (no acceleration). Unbalanced forces changes the motion of the object (acceleration).
