Question

How does acceleration relate to distance?

Answer 1

Hint : Acceleration is defined as the rate at which an object's velocity changes. According to Newton's second law, a body's acceleration is the sum of all the forces acting on it. Acceleration is a vector quantity defined as the frequency with which the velocity of a body changes. Distance is defined as an object's total movement without regard for direction.

Complete Step By Step Answer:
The distance traveled by an object with constant acceleration is directly proportional to the square of the time traveled. To calculate acceleration, divide velocity by time — or, in SI units, divide the meter per second [m/s] by the second [s]. Dividing distance by time twice is equivalent to dividing distance by time squared. As a result, the SI unit of acceleration is the meter per second square.
The second derivative of distance with respect to time is acceleration. If the movement is only in one dimension, $(x)$ we can write,
$a=\dfrac{{{d}^{2}}x}{d{{t}^{2}}}$
The velocity derivative is the first derivative. This determines how quickly the distance changes. If someone moves away from you at one meter per second, the distance between you and them changes by one meter every second.
$v=\dfrac{dx}{dt}$
If the velocity remains constant, the second derivative is zero. Zero acceleration denotes that the velocity is constant. However, if the other person is either accelerating or decelerating, the second derivative will be non-zero, and we will say that they are accelerating. We could say they are decelerating if the acceleration reduces the magnitude of the velocity.
When a ball is thrown into the air, it experiences constant downward acceleration. The velocity in the upward direction is initially high (usually positive). The velocity of the object decreases to zero at the top of its flight. The ball then begins to fall, and its velocity increases (or decreases) until it is caught or hits the ground. Despite the fact that the distance and velocity are constantly changing, the acceleration of an object in freefall is always constant.

Note :
Because accelerating objects' velocity is constantly changing, the distance traveled/time is not a constant value. A falling object, for example, typically accelerates as it falls.
