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 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

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 would the graph look like on a position verse time plot with constant acceleration?

If the constant acceleration is positive, the graph would be an exponential (x2) graph. If there is constant acceleration, then velocity is always increasing, making the position change at an ever increasing rate.

How would a graph of negative and positive acceleration differ?

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).

How can a position time graph show if an object has constant acceleration?

With a straight line.

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 can a position-time graph show if an object has constant acceleration?

By showing a straight line.

What shape do you expect for a graph showing the position of a motorcycle versus time if the motorcycle is speeding up with a constant acceleration?

The position versus time graph is parabolic.

The graph of velocity versus time for an object with a constant negative acceleration would be?

The line would decrease as the time increased and it would stop once it touched the X axis because you cannot have a negative velocity. This graph would represent an inverse relationship between velocity and negative acceleration/

Speed time graph?

A speed vs. time graph could also be called a graph of acceleration. This graph will have a constant slope if the increase in speed is constant. It can also form a curved line if there is increasing or decreasing acceleration.

What will be the nature of velocity-time graph for a uniform motion?

The nature of uniform motion for a velocity-time graph is graphed as a horizontal straight line. Uniform motion is unaffected by acceleration (line does not curve), which means that it goes up or down in a constant rate on a position-time graph. Velocity= the slope of a position-time graph. So, if the motion is constant on a position-time graph then the velocity of the uniform motion is constant on a velocity-time graph. Lauren "Physics above all!"

What does a horizontal line on a velocity time graph show for acceleration?

If the graph is a horizontal line, then the velocity is constant, and acceleration is zero.

What is a position versus time-squared graph?

If you have an object that is accelerating, then a position vs. time graph will give you a parabola which is pretty but is very hard to measure anything on - especially hard to measure the acceleration (or the curve of the line). If however, you graph position vs. time squared, you get a nice straight line (if you have constant acceleration) and therefore, you can measure the slope and get the acceleration. Remember: x = 1/2at2 so if you graph x vs. t2 then the slope = 1/2 a or a = 2*slope No matter what you are measuring, you always want to graph a straight line. hope that helps

When the acceleration is not in a straight line on a graph what does this indicate?

That the force that causes the acceleration is not constant.

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.

How is constant acceleration represented on a velocity-time graph?

It would be straight line as the slope of the line is constant acceleration. V = at

On a V-t graph how does constant acceleration appear?

On a graph of speed versus time, where time is plotted along the horizontal (X) axis and speed along the vertical (Y) axis: -- constant speed (zero acceleration) produces a straight, horizontal line; -- constant acceleration produces a straight, sloped line; the slope of the line is equal to the acceleration; -- if the acceleration is positive, the line slopes up to the right (speed increases as time increases); -- if the acceleration is negative, the line slopes down to the right (speed decreases as time increases).

How is deceleration represented on velocity time graph?

Constant line with slope = acceleration Deceleration means the slope is negative\ (higher on the left\)

How is speed and acceleration represented on a graph?

On a speed versus time graph, acceleration is represented by the line on the graph. If acceleration is constant, the line cuts through equally between the axis and starts from the zero point.

How does slope compare with acceleration due to gravity?

Acceleration due to gravity (free fall) is a downward (negative) motion. On a position-time graph, the slope representing free fall will be a downward curve. On a velocity-time graph, the slope representing free fall will be a straight line with a negative (downward) slope.

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.

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


Is velocity is the slope of the acceleration vs time graph?

Velocity is NOT the slope of the acceleration vs. time graph. Velocity is the area under the acceleration vs. time graph. Velocity is the slope of a position vs. time graph, though. For you Calculus Junkies, v = the integral of acceleration with respect to time.

What is the slope of constant velocity?

The Slope (which represents acceleration) of a constant velocity graph is Zero.

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

Acceleration is negative.

What does a horizontal line on a acceleration graph mean?

This means that it has a constant acceleration. It DOES NOT mean that the object is at rest.
