Want this question answered?
A period of constant positive acceleration;a second period of zero acceleration; a third period of constant negative acceleration.
The answer depends on what is plotted on the graph and what is happening with the acceleration then.
The answer depends on the variables in the graph! In a graph of age against mass there is nothing that represents acceleration.
Acceleration is how fast you get up to speed.
Acceleration is indicated on a speed/time graph.
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).
AB
The answer depends on whether the graph is that of speed v time or distance v time.
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.
A period of constant positive acceleration;a second period of zero acceleration; a third period of constant negative acceleration.
false
false
constant positive acceleration
Ahorizontal line on a velocity vs time graph does not indicate any acceleration because there is no slope. Speed remains constant.
Acceleration=change in y graph/change in x graph
an up ward slopeing straight line
