Matto120 Kinematics is the study of the motion of mechanical points, bodies and systems without consideration of their associated physical properties and the forces acting on them. The study is often referred to as the geometry of motion, and it models these motions mathematically using algebra.

    Kinematics is the study of motion, without any reference to the forces that cause the motion. It basically means studying how things are moving, not why they're moving. It includes concepts such as distance or displacement, speed or velocity, and acceleration, and it looks at how those values vary over time.

    There are four basic kinematics equations:
    v = v 0 + a t.
    Δ x = ( v + v 0 2 ) t.
    Δ x = v 0 t + 1 2 a t 2.
    v 2 = v o 2 + 2 a Δ x.

    It can be noticed that if any four of the variables are given, we can easily calculate the fifth variable using kinematic equations.

    For example, if it is given that a car is travelling and it accelerates from its resting position with an acceleration of 6.5 m/s2 for a time span of 8 seconds, reaching a final velocity of 42 m/s, east and a displacement of 120 m, then the motion of this car is fully described. Now, if anyone of this information was not provided, we could have easily calculated it with the help of kinematics equations.

    Matto120 its not u its @Ronaldo dw u js focus on studying, and EVERYONE ELSE STOP THIS BS AND PREPARE, GET REAL WE HV LIMITED DAYS AND WE SHOULD ALL GET OUR PREFERENCES SO STFU AND STUDY LIKE HELLLL

        Matto120 not ur fault, there are stupid ahh ppl in this server who need to take things serious frfr
