If the speed/time graph slops negatively, that's an indication that the speed
is decreasing, i.e. the object is slowing down. The negative slop is also called
negative acceleration, since acceleration is the rate of change of velocity.
I Dont know sombody help me on this an I'm on a quiz (:
Abduction
An object is moving if its position is changing with respect to a reference point over time. This can be observed by visually tracking the object's motion or using instruments to measure its displacement.
An downward sloping diagonal line on a position vs. time graph indicates constant negative acceleration or deceleration. This means that the object is moving in the negative direction and slowing down over time.
a high pressure system is moving into an area
No. It always indicates that the object is not accelerating.
Not necessarily. A zero slope on a velocity vs time graph indicates that the object's velocity is constant, not that it is not moving. If the velocity is zero and remains zero, then the object is not moving.
A position-time graph showing positive acceleration indicates that the object is moving in the positive direction and its speed is increasing over time.
If an object stops moving, the position-time graph will show a horizontal line at the position where the object stops. This indicates that the object is at rest at that specific position, with no change in its position over time.
from the point at rest the line will be curved and going diagonally upwards visual: http://www.gravitywarpdrive.com/General_Relativity_Images/Falling_Ball_Graph_Distance.gif

A positive acceleration position-time graph indicates that the object is speeding up or moving in the positive direction.
The slope of a position-time graph measures the velocity of an object. A steeper slope indicates a higher speed, while a flatter slope represents slower movement. If the slope is positive, the object is moving in the positive direction, and if the slope is negative, it is moving in the opposite direction. A zero slope indicates that the object is at rest.
Assuming position is on the y axis and time is on the x axis, a positive slope means the position has increased over time.
A solid yellow line marking always separates traffic moving in opposite directions. It indicates that passing is not allowed due to the potential for head-on collisions.
The measure between the starting and ending position of a moving object is called displacement. Displacement is a vector quantity that indicates the change in position from the initial point to the final point of an object's motion. It includes the direction and magnitude of the movement.
A slope of zero indicates that the object is not moving, or it is moving at a constant velocity without changing speed or direction. This means there is no acceleration, and the object remains at a consistent position or motion.
