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.

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 3 things does acceleration refer to in science?
Speeding up, Slowing down & Changing direction.
What is positive and negative acceleration?
Positive acceleration = speeding up. Negative acceleration = slowing down.
How do you find out the direction of angular accelaration?
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
What is meant by positive acceleration and negative acceleration?
Positive acceleration = speeding up; speed increasing in the direction you're moving.Negative acceleration = slowing down; speed decreasing in the direction you're moving,or speed increasing in the opposite direction.

Why car still accelerates after slowing down?
Acceleration is a change in velocity. Assuming a constant direction, if you're speeding up that is positive acceleration. If you are slowing down, that's negative acceleration. Either way you are accelerating.
What are the different types of acceleration?
-- changing direction of motion, like around a curve or a corner -- slowing down -- speeding up
What is negative and acceleration?
Positive acceleration = speeding up. Negative acceleration = slowing down.
When does an object have no acceleration?
When it is stationary, or when the velocity is constant. If it is speeding up or slowing down, it has acceleration.
What is positive acceleration negative acceleration?
Positive is speeding up and negative is slowing down
Can there be acceleration in the body even when the body is not speeding up or slowing down?
Yes. Acceleration is change in velocity. Velocity is either change in speed or change in direction. If you fix the speed, change in direction can account for change in velocity, i.e. acceleration.
