Answer #1:
The y intercept should be zero because of Newton's second law. Force and
acceleration are directly proportional. The X intercept indicates that there is
some force required to overcome friction if friction is not negligible. This value
is the force required to accelerate the object usually very small.
===============================
Answer #2:
It's even easier than that. The graph had better pass through the origin,
because zero force on an object means it can't be accelerating, and zero
acceleration of an object means there can't be any net force acting on it.
Go back and read Answer #1 above very carefully. It correctly says that the
y-intercept is zero. But doesn't that mean that the graph must go through the
origin, and that the x-intercept is therefore also zero ? I'm just sayin . . .

What physical quantity the area under force-displacement graph represent?
It is the work done or the energy utilised
What would be the shape of speed time graph of a body moving with variable speed?
Distance-time graph will show a straight line with a positive slope. Speed-time graph will show a horizontal line at the uniform speed. Acceleration-time graph will show a horizontal line at a = 0.
A scientist wants to display how the number of frogs in a pond gradually declined over a 10-year period. What sort of visual display should the scientist use?
a line graph
Is every tree a bipartite graph?
Yes, every tree ia a bipartite graph (just see wikipedia).
What is a hamiltonian path in a graph?
A Hamiltonian path in a graph is a path that visits every vertex exactly once. It does not need to visit every edge, only every vertex. If a Hamiltonian path exists in a graph, the graph is called a Hamiltonian graph.
Does the force vs acceleration graph goes through origin?
No, in general, the force vs acceleration graph does not always pass through the origin. This is because there may be a non-zero force acting on an object even when it is at rest. The presence of a non-zero force at rest would lead to a non-zero intercept on the force vs acceleration graph.
What variables represent force mass and acceleration?
Usually time but it could depend on the specific graph.
Y16500-1500x what does the y intercept of the graph represent?
18000
How can you represent acceleration on a linear graph?
The answer will depend on the variables plotted on the graph!
Plot the graph of force vs acceleration?
Acceleration is directly proportional to applied force. When acceleration increases, force also increases. If the force is tripled, the acceleration will also be tripled. Note that the mass must remain constant...
Why is the area under the curve for the force graph equal to the impulse?
It is not, if it is a graph of force against acceleration.
What does a slope of a time graph represent?
The slope of a velocity-time graph represents acceleration.
How do you make a force time graph from acceleration time graph?
You might assume that acceleration is proportional to force - specifically, using Newton's Second Law. However, you would need to know the mass on which the force acts - otherwise, you simply don't have enough information.
What does area of acceleration time graph represent?
change in velocity
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.
What does slope of a speed time graph represent?
The slope of a velocity-time graph represents acceleration.
What does the slope of velocity -time graph represent?
Magnitude of acceleration (but conveys no informationregarding acceleration's direction).
