Kinematics concepts

if it changes:

Kinematics is the study of the motion of points, objects, and groups of objects without considering the causes of its motion.

Linear, curvy or parabolic

A vector is any quantity that has both magnitude and direction, whereas a scalar has only magnitude.

URM or UARM

You need to differenciate both

The location of an object at any given time.

In order to describe an object’s motion, you need to specify its position relative to a convenient reference frame.

MOTION

URM, Uniform Rectilinear Motion

In a rectilinear motion, the trajectory is a straight line. (such as the free fall of an apple from a tree). For a uniform rectilinear motion, the trajectory is a straight line and the velocity is constant.

UARM,Uniformly Accelerated Rectilinear Motion

The accelerated movement is a movement in which velocity changes with time. If there is an increase in velocity, the acceleration is positive and If the velocity diminishes, the acceleration is negative (deceleration).

Kinematics is the branch of mechanics that deals with motion without taking into account the forces that cause it. It is an essential aspect of engineering and physics, used to describe, predict and understand motions. This includes the motion of objects as well as the motion of particles.

Difference:

Distance is the total path covered by the object in motion, irrespective of the direction of the path. Distance is known as a scalar quantity as only the path length covered is measured and the direction of motion is not considered. The distance can never be zero or negative, it is only be positive. Displacement is defined as the total change in the position of the object along with the direction of motion. Displacement is known to be vector quantity as along with the magnitude of the changed position, the direction of the motion is also taken into account. Displacement can be positive, negative, or zero.

What is the difference between distance and displacement? Whereas displacement is defined by both direction and magnitude, distance is defined by magnitude alone. Displacement is an example of a vector quantity. Distance is an example of a scalar quantity. A vector is any quantity with both magnitude and direction. Other examples of vectors include a velocity of 90 km/h east and a force of 500 newtons straight down.

In mathematics, physics, and engineering, a vector is a geometric object that has a magnitude (or length) and direction and can be added to other vectors according to vector algebra. The direction of a vector in one-dimensional motion is given simply by a plus (+) or minus (−) sign. A vector is frequently represented by a line segment with a definite direction, or graphically as an arrow, connecting an initial point A with a terminal point B, as shown in.

Vector representation: A vector is frequently represented by a line segment with a definite direction, or graphically as an arrow, connecting an initial point A with a terminal point B.Some physical quantities, like distance, either have no direction or no specified direction. In physics, a scalar is a simple physical quantity that is not changed by coordinate system rotations or translations. It is any quantity that can be expressed by a single number and has a magnitude, but no direction. For example, a 20ºC temperature, the 250 kilocalories (250 Calories) of energy in a candy bar, a 90 km/h speed limit, a person’s 1.8 m height, and a distance of 2.0 m are all scalars, or quantities with no specified direction. Note, however, that a scalar can be negative, such as a −20ºC temperature. In this case, the minus sign indicates a point on a scale rather than a direction. Scalars are never represented by arrows.
