Negative velocity usually means going in the opposite direction (i.e. reverse or backwards).
False. It means it is slowing Down!
When velocity is negative, it means that the object is moving in the opposite direction of its positive velocity.
In a physical context, a negative velocity indicates that an object is moving in the opposite direction of its positive velocity.
No. A negative slope means that the object is slowing down. If the object were not moving, then its velocity would be zero. The graph would be a straight horizontal line that just lays there on the time axis.
A vertical line segment on a velocity versus time graph represents an instantaneous change in velocity, which is physically impossible. It would mean that an object goes from one velocity to another instantly, without any acceleration. In reality, objects need time to change their velocity due to the presence of acceleration or deceleration.
False. It means it is slowing Down!
If acceleration is negative the graph looks like a upside U and decreases in value as time continues If acceleration is constant the graph is a straight line (linear) at 0 or whatever the velocity is
That an object is losing speed. It is experiencing negative acceleration.
velocity is nothing but speed of a body in the given direction. suppose if body is moving with constant velocity then VT graph will be parallel to the X -axis, if not then the VT graph is not parallel to the X-axis it means then object is moving with different velocity or it has its dierection or both velocity and aswell as direction.
When velocity is negative, it means that the object is moving in the opposite direction of its positive velocity.
velocity
Acceleration , which is change of velocity over time.
In a physical context, a negative velocity indicates that an object is moving in the opposite direction of its positive velocity.
No. A negative slope means that the object is slowing down. If the object were not moving, then its velocity would be zero. The graph would be a straight horizontal line that just lays there on the time axis.
The slope of a straight line on a position vs. time graph represents the object's velocity. A steeper slope indicates a faster velocity, while a shallower slope indicates a slower velocity. The slope can be positive for motion in the positive direction and negative for motion in the negative direction.
Time is plotted on the X-axis. Speed or velocity is plotted on the Y-axis. A straight horizontal line on a speed-time graph means that speed is constant. It is not changing over time. A straight line does not mean that the object is not moving!
That slope is the 'speed' of the motion. If the slope is changing, then the speed is changing. That's 'accelerated' motion. (It doesn't matter whether the speed is growing or shrinking. It's still 'accelerated' motion. 'Acceleration' does NOT mean 'speeding up'.)
