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 is movement that occurs along a straight line?
Motion with uniform velocity. * * * * * There is absolutely no reason for the velocity - or even speed - to remain constant. It is linear motion an that is all that there is to it.
A toy car accelerates from at a constant rate and covers 75 m along a straight line in 30 seconds what is the final velocity of the car?
The question cannot be answered because a part of it is missing. A toy car accelerates from ... WHAT ... at a constant rate ...
Examples problem in motion along straight line?
A problem in motion along a straight line is a problem that takes place in one dimension. An example problem is an object on a straight conveyor belt.
What is rectilinear motion?
The motion along a straight line is known as rectilinear motion.
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.
Describe the motion of a bus whose acceleration is 0 but whose speed is not 0.?
The bus is in steady motion along a straight line at a constant velocity.
Define isocost line?
A line along which the cost of something -- usually a combination of two factors of production -- is constant. Since these are usually drawn for given prices, which are therefore constant along the line, an isocost line is usually a straight line, with slope equal to the ratio of the (factor) prices.

Motion with uniform velocity. * * * * * There is absolutely no reason for the velocity - or even speed - to remain constant. It is linear motion an that is all that there is to it.
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).

Descrbe a real world situation where there is zero acceleration but some velocity.?
-- a car on cruise control rolling along at a constant speed on a straight section of highway -- a golf ball or squash ball rolling across the gym floor at a constant speed
Is utility constant along a demand curve?
utility is not constant along the demand curve
In what condition average velocity is equal to average speed give an example?
When an object is moving along a straight line at a variable speed, we can express the magnitude of the rate of motion in terms of average velocity.It is the same way as we calculate average speed.
What do you mean by uniform and non uniform motion?
HEYAnswer:"Uniform" motion is motion with a constant speed in a straight line. Speed ordirection are not changing.If a body moving along straight line travels unequal distances in equal intervals of time, the body is said to be in Non uniform motion
What does the graph of acceleration vs time look like for something going a constant way?
Because acceleration is the derivative of velocity, you can determine what an acceleration vs. ... t graph are straight and horizontal, i.e. the object moves at a constant velocity, the slopes of those lines are 0 , and so the a vs. t graph should show a straight, horizontal line at y=0 (along the x -axis).
If a force is exerted on an object is it possible for that object to be moving with constant velocity?
Velocity is a vector quantity in which both magnitude and direction must be taken into consideration. For an object to have constant velocity, it is necessary that both the magnitude and the direction of the velocity must be constant. Even if either magnitude or direction is variable, velocity will not remain constant. On the other hand, speed remains constant if direction is changed and magnitude is kept constant, as speed is a scalar quantity.For an object to have constant velocity, it is necessary that the object move at a constant speed and not change course. That object must move in a straight line to have a constant velocity.
