An acceleration is a change in velocity. Velocity is a vector quantity; it tells you about both an object's speed and its direction of travel (vectors are often represented as arrows; the length of the arrow is the magnitude, here the speed, and it points in the relevant direction). So you can see that a change in either an object's speed or direction counts as a change in velocity, and is therefore an acceleration.

If an object accelerates in the same direction which it is moving how is it speed affected?
The speed of the object will increase.
If an object accelerates in the same direction in which it is moving how is its speed affected?
The speed of the object will increase.
Describe a situation in which an object accelerates without changing speed?
Acceleration is the rate of change of velocity over time, so velocity must always be changing if the object is accelerating. HOWEVER, you said speed which means only magnitude, not direction. If you stay the same speed, but change direction then you are accelerating. Simple answer: when you are going the same speed in a circle - velocity changes, therefore acceleration changes.
What is the relationship between an object's acceleration and the direction of the force on the object?
If an object is increasing in speed, the acceleration is positive and the force is in the direction of travel. If the object is slowing down, the acceleration is negative and the force is acting against the direction of movement.
The momentum of an object is in the same direction as what?
The velocity of the object.
If an object accelerates in the same direction which it is moving how is it speed affected?
The speed of the object will increase.
When a object accelerates in the same direction as its motion it has?
change in velocity
If an object accelerates in the same direction in which it's moving how is its speed affected?
The speed of the object will increase.
If an object accelerates in the same direction in which it is moving how is its speed affected?
The speed of the object will increase.
When an object accelerates how does air resistance respond?
It basically pushes the same amount of force in the same direction and in the same speed.

Does friction move in the same direction as or in opposite direction as the object?
The force of friction ALWAYS acts in the direction exactly opposite to the directionin which the object is moving.If the friction force acted in the same direction as the object's motion, then youwould want to have as much friction as possible, because that would help youmove the object with less fuel.
Does heat always flow in the same direction?
Yes, Heat always flows from the coldest to Hottest point in an object
What is the relationship between an object's acceleration and the direction of the force on the object?
If an object is increasing in speed, the acceleration is positive and the force is in the direction of travel. If the object is slowing down, the acceleration is negative and the force is acting against the direction of movement.
How can an object change it direction?
Some force is applied to the object in any direction not the same as the present direction.
The momentum of an object is in the same direction as what?
The velocity of the object.
When somthing move does it always change in position and direction?
When something is moving or in motion, it can be changing position and direction. However, the object does not have to be doing both at the same time.
