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.
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

Can a position time graph tell in which directionthe displacement of an object is?
Yes. If the slope is positive, the direction of the displacement is positive (e.g. north, east, or right). If the slope is negative, the direction of the displacement is negative (e.g. south, west, or left).
How can displacement be negative?
Displacement is a vector quantity, which means it has a magnitude (size) and a direction, compared to a scalar quantity which only shows size. A negative displacement simply means that the person or object is going in a negative direction, or returning.ORYes it can be -ve because with displacement, sign indicates direction. Usually right and up are designated as positive while left and down are designated as negative, but this can be changed as long as one is consistent.So in most cases, if the displacement is negative it means you are moving in the opposite direction/backwards.

What the distance and direction of an object from the starting point?
Displacement.
What is the distance and direction of an object from starting point?
Displacement.
Is costheta is a vector?
No. Cos theta (Cos θ) is a trigonometric function. A vector is any physical quantity which has both magnitude and direction. For example, Displacement. Displacement has a magnitude like 240m or 0 or 13 m, etc. It also depends on the direction. If an object moves along the positive direction of x-axis, then the displacement will have a positive sign and if it moves along the negative direction of x-axis, then displacement will be negative. Thus, it has both direction and magnitude and so is a vector. Cos theta is a trigonometric function, strictly speaking.
