What is kinematics ???
explain !!

the branch of mechanics concerned with the motion of objects without reference to the forces which cause the motion.

the features or properties of motion in an object.

plural noun: kinematics

Origin

mid 19th century: from Greek kinēma, kinēmat- ‘motion’ (from kinein ‘to move’) + -ics.

the branch of mechanics concerned with the motion of objects without reference to the forces which cause the motion.

the features or properties of motion in an object.

plural noun: kinematics

Origin

Kinematics is the study of motion of a system of bodies without directly considering the forces or potential fields affecting the motion. In other words, kinematics examines how the momentum and energy are shared among interacting bodies.

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
