This depends on what the graph represents. If it is a graph of velocity on the vertical and time on the horizontal, then if acceleration is at a constant rate, the graph will be a straight line with positive slope (pointing 'up'). If acceleration stops, then the graph will be a horizontal line (zero acceleration or deceleration). If it is deceleration (negative acceleration), then the graph will have negative slope (pointing down).

What information does the slope of a speed time graph provide?

The slope of a speed-time graph represents the acceleration of the object. A positive slope indicates acceleration in the positive direction, a negative slope indicates acceleration in the negative direction, and a zero slope indicates constant speed.


What part of the graph represents uniform positive and negative acceleration Calculate this acceleration.?

The answer depends on whether the graph is that of speed v time or distance v time.


What does the slope of the tangent to the curve on a velocity-time graph measure?

The slope of the tangent to the curve on a velocity-time graph represents the acceleration of an object. Positive slope indicates acceleration in the positive direction, negative slope indicates acceleration in the negative direction, and zero slope indicates constant velocity.


What type of acceleration does a trapezium on a velocity time graph represents?

A period of constant positive acceleration;a second period of zero acceleration; a third period of constant negative acceleration.


How does a graph showing speed differ from a graph showing acceleration?

Speed can be shown on a graph of position versus time, and acceleration can be shown on a graph of speed versus time.


What happens to acceleration when speed decreases on a speed time graph?

Acceleration is negative.


If the acceleration is increasing with time will the velocity graph be a straight line concave up or concave down?

If acceleration is increasing with time, the velocity graph will be concave up. This is because a positive acceleration causes the velocity to increase over time, resulting in a curve that opens upward on the velocity-time graph.


When the slope of v t graph is negative and constant what is the nature of acceleration?

acceleration is the slope of the v t graph... so the acceleration is constant and negative. In other words, the object is slowing down at a constant rate.


What does the slope of a velocity vs time graph show you?

The slope of a velocity vs time graph represents the acceleration of the object. A positive slope indicates acceleration in the positive direction, a negative slope indicates acceleration in the negative direction, and a horizontal line indicates constant velocity.


In the graph which region shows nonuniform positive acceleration?

A region with nonuniform positive acceleration on a velocity-time graph would appear as a curved or non-linear section where the velocity is increasing at a variable rate.


A negative slope on the velocity vs. time graph indicates a negative acceleration?

True


Can acceleration ever be negative?

Yes, acceleration can be negative when an object is slowing down or changing direction in the opposite direction of its current motion. Negative acceleration is often referred to as deceleration.
