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).

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

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 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.


Is a negative slope on the velocity vs time graph indicates that the objects is not moving?

A negative slope, called 'a negative gradient' by the intelligent, on a Velocity-Time Graph shows the deceleration of the object. This negative gradient is the positive deceleration and the 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 type of motion is occurring when the slope of a velocity vs time graph is changing?

A motion described as a changing, positive velocity results in a sloped line when plotted as a velocity-time graph. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line). If the acceleration is negative, then the slope is negative (i.e., a downward sloping line).


Can acceleration ever be negative?

Acceleration is negative when the object is moving in the opposite direction. on a graph the line would be in the negative quadrant.


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

Acceleration is negative.


How is declaration represented on a velocity time graph?

Deceleration (negative acceleration) is represented by a negative slope on a 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.


In the graph which region shows nonuniform positive acceleration?

AB


What does the position vs time graph look like if acceleration is constant and negative?

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


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