The equations of motion are applicable only when the body moves with uniform acceleration. A body under constant acceleration is uniformly accelerated motion.
Thus, the magnitude of displacement may be equal to or smaller than that of distance.
For a body starting from rest, the displacement in 10 seconds, when it acquires 4 ms^{1} in 2 seconds is______.
v = u + at
or = 2m/s^{2}
s = ut +
= 100 m
On a velocitytime graph, a horizontal straight line corresponds to motion at_______.
It is horizontal so, angle is zero and also acceleration is zero. Hence constant velocity.
For a uniformly accelerated body with initial and final velocities as u and v ms^{1}, the average velocity is _______.
Average velocity of an object is equal to its final velocity plus initial velocity, divided by 2.
Therefore, the answer is, (u + v) / 2
In figure A, we can see that the object continues to remain at a fixed place while the time keeps running. So, the object is at rest, because the object does not change its position with time.
"Displacement" is the quantity that is measured by the area occupied under the velocitytime graph. Moving something or someone from its place or position is called displacement.
The slope of a velocitytime graph represents the acceleration of the object. So, the value of the slope at a particular time represents the acceleration of the object at that instant.
