How many times does a straight line pass through the x-axis?
A straight line passes through the x-axis one time, if its slope is non-zero, or not at all, if its slope is zero.
What does a zero slope line look like?
A straight, horizontal line.
What is the meaning of a line segment?
A line segment is a straight line that has an endpoint on both sides (look below). ----
What is the formula for slope of a straight line?
the formula for slope is y=mx+b, a horizontal line has the slope of zero and the slope of a vertical line can be answered as undefined
What is symmetrical airfoil?
A symetrical airfoil is an airfoil that has the same shape on both sides of its centerline and in this type of airfoil : the centerline is thus straight the chord line is the center line the maximum camber is zero the camber ratio is zero
Does displacement have to be in a straight line?
Displacement of a straight line is zero...
Why the straight line in the graph doesn't start from zero?
Unless it is a direct proportion, the straight line does not have to start from zero.
When velocity is positive and acceleration is zero what happens to an objects motion?
When acceleration is zero, then the object is moving in a straight line with constant speed. (That's the effective meaning of constant velocity.)
For motion along a straight line a horizontal line on a speed over time graph indicates graph indicates that what is zero?
For motion at constant speed along a straight line, the acceleration is zero.
What angle is Zero degrees?
zero degrees is not an angle because there is degrees
How can you tell if a slope is zero or undefined?
A slope is 0 if it is a straight horizontal line. A slope is undefined if it is a straight vertical line.
Can an object with non zero force move at constant speed in straight line?
Yes, if the net force acting on the object is zero. When the forces are balanced, there is no acceleration, and the object will continue to move at a constant speed in a straight line according to Newton's first law of motion.
How many times does a straight line pass through the x-axis?
A straight line passes through the x-axis one time, if its slope is non-zero, or not at all, if its slope is zero.
What is the acceleration of car that travels in a straight line at constant speed?
Straight line at a constant speed = no acceleration
What speed is a horizontal straight line motion on a position-time?
Zero.
If a straight line graph has a gradient of zero it must be horizontal?
120?
What is the slope of line y equals -2?
Slope = zero. The line is horizontal, parallel to the x-axis.
