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.

∙ 11y agoThe acceleration of an object is directly proportional to the size of the force
applied to it, and in the same direction.
If there's more than one force applied to the object at the same time, then the
various forces can always be added as vectors, and handled as if they were all
one single force, called the "net" force. Then, the object's acceleration is directly
proportional to the size of the net force, and in the same direction.
Force applied = mass times acceleration

∙ 8y agoThe direction of an object's acceleration is the same as the direction of the net force acting on the object.

What is the direction of average acceleration?
The direction of average acceleration is downwards, in the direction of gravity. This is because gravity affects all objects, even objects that are moving in other directions.
What do you call it when an objects velocity changes?
A change in an objects velocity is called acceleration. Velocity is defined as an objects speed of travel AND its direction of travel. Acceleration can change only an objects speed, only its direction or both. If there is no acceleration acting on the object, then the velocity remains constant.
Both speed and acceleration include the direction of an objects motion true or false?
This is not true. Acceleration includes direction, but speed does not. Speed in a particular direction is called velocity.
Acceleration is a change in speed or?
Acceleration is the change in an ogjects speed or a change in an objects direction of motion or both of these. If instead of speed you use the word velocity , which is both an object's speed and its direction of motion, then you could say "acceleration is the change in an objects velocity" and that would cover all the possibilities in one statement.
How are the direction of the an objects acceleration and direction of the same object change in velocity related?
if the force isnt inline , resolve into axial and lateral forces, the original force bieng the hypotonuse

What is the relationship between the mass of an object and the objects acceleration?
Momentum=mass*velocity
If objects get faster with time the direction of the acceleration is?
The acceleration is positive.

When you know both the speed and direction of an objects of an objects motion you know the?
I'm pretty sure its the acceleration. If its not that, its the Velocity.
How do unbalanced forces affect objects?
An unbalanced force will cause acceleration in the direction of the force.
Why does the acceleration of an object rolled down an incline increase as the angle of incline increases?
The contribution of the acceleration of gravity in the direction of motion increases as the angle of the incline increases. Or in other words, as the angle between the direction of motion and the force of gravity goes to zero, the acceleration of the object goes to the gravitational acceleration. a = g cos(theta) Where theta is the angle between the direction of motion and verticle, which is in fact (theta = 90 - angle of the incline)Where a is the acceleration of the object down the incline plane and g is the acceleration due to gravity. Theta is the angle between the direction of motion of the accelerating object and the acceleration of gravity. Initially, the angle between a and g is 90 degrees (no incline) and therefore g contributes nothing to the objects acceleration. a = g cos(90) = 0 As the angle of the inclined is increased, the angle between a and g approaches zero, at which point a = g. With no other forces acting upon the object, g is its maximum acceleration.
Both speed and acceleration include the direction of an objects motion?
Yes! In most problems direction needs to be defined as either positive or negative.
