False. It means it is slowing Down!
A negative slope on a velocity-time graph indicates a decreasing velocity over time, which means the object is slowing down. As time increases, the velocity decreases.
No. It always indicates that the object is not accelerating.
At that moment, the object isn't moving - but since the velocity is changing, it soon will.

A negative slope on a velocity-time graph indicates a decreasing velocity over time, which means the object is slowing down. As time increases, the velocity decreases.
Yes. It can be negative. With regards to 1 dimensional motion, if it is negative it indicates that the object at that particular instant in time is moving towards smaller values of x.
No. It always indicates that the object is not accelerating.
No. It always indicates that the object is not accelerating.
This was the essential question on a homework assignment. Speed tells how fast an object is moving but it does not tell the direction. Velocity tells how fast an object is moving and it also tells the direction. When velocity is positive, the object is moving up. When velocity is negative, the object is moving down.
At that moment, the object isn't moving - but since the velocity is changing, it soon will.
No. The velocity of an object is how fast it is moving as well as the direction of the motion. So when considering one dimension, the velocity can be positive or negative. The speed of the object is simply the magnitude (absolute value, in the case of one dimension) of the velocity, with no direction. Acceleration is the change in velocity and does include direction. So if an object has a positive velocity (in one dimension) and its speed increases, the acceleration is negative. However, if the speed of an object moving the negative direction increases, then the acceleration is negative, because the velocity becomes "more negative."
False. It has negative acceleration.
its false
Yes, "velocity" is a vector so it not only has magnitude but also direction. By convention, an object moving from left-to-right or upward is moving in a positive direction while an object moving right-to-left or downward is moving in a negative direction. "Speed" is a related term but it is a scalar. As such, it has only magnitude. A speed cannot be negative.
