The slope (gradient) of a speed v time graph is acceleration.
If the graph is a straight line, then the acceleration is constant. if the slope is 0 (ie the line is horizontal) then the acceleration is 0, and the object is moving with a constant speed (which can be 0, ie the object is stationary).
If the graph is "slanted" then depending upon which way the line is "slanted" the object is accelerating or decelerating (the steepness of the slope gives the rate of this).
So the object is moving with constant acceleration and either speeding up or slowing down - which, and by how much, depends upon the gradient of the graph.
If its slanted up its accelerating, if down its decelerating.
A straight slanted slope on a velocity-time graph indicates that the object is moving with a constant acceleration.
The motion along a straight line is known as rectilinear motion.
The trajectory of the motion is a straight line.
If an object moving along a straight line,path,track etc.It,s motion is said to be straight line motion
I believe linear motion is simply straight motion because linear means straight
Motion in a straight line.
Linear motion is movement that happens in a straight line. Drawing with a straight-edge is considered to be linear motion.
The motion of a dot (spot, point) on the outer edge of a tire on your car as it drives down a smooth, straight road.
