Velocity :- The rate of change of displacement is called velocity. or a speed with direction is called velocity.
➡ ➡
V = d/t . (here v = velocity d = displacement t= time) Velocity is vector quantity
displacement :- The minimum distance from initial position to final position is called displacement.
uniform motion :- If an object covers equal distance in a equal interval of a time then it is said to be having uniform motion.
non - uniform motion :- If an object covers unequal distance in a in equal interval of a time is called non uniform motion.
motion :- If an object change it position with respect to the time then it said to be in a motion
rest :- If an object do not change its position with respect to the time is said to be in a rest.
speed :- The change of the position of an object with respect to the time is called speed.
acceleration :- The rate of change in velocity is called acceleration.
a = ∆V/t
distance :- The total path traveled by an object is called distance .

3 laws of motion.
inertia :- The tendency to do nothing or still remain unchanged .
for example :- You say sit me on chair but i say I do not sit on this is my inertia.
1 law of motion :- If an object is in a motion it try still remain in a motion if an object is in rest it try to still remain in rest if it is in a particular direction it try to still remain in that direction unless we apply the external force.
2 law :- If we accelerate the body by applying the force then this acceleration is directly proportional to the applied force and universally proportional to the mass of an object .
F = ma
here ,
F -------> Force
m -------> mass
a ------> acceleration
3 rd law of motion :- For every action, there is an equal and opposite reaction.
__________________________________________________________
Formulas of motion ,
1) a = v-u/t
2) s = ut + at²/2
3) v² = 2as + u²
here,
a = acceleration
s = distance traveled by an object
u = intial speed or velocity
v = final speed or velocity
t = time

Friction :- The force that opposes the motion of an object is called friction. It is always opposite to the motion of an object

Velocity is defined as the displacement of an object in unit time
2. Displacement is the shortest distance between the initial point and the final point.
3. When an object covers equal distanc ein equal intervals of time.
4. when an object covers unequal distance in equal intervals of time
5. The resistance that on object or surface encounters while moving on one another
6. the movement of an object with respect to a fixed point
The 3 laws of motion
1. Every body in the nature remains in the state of rest or motion along a straight line unless an external unbalanced force acts on it
2.The rate change of momentum ina an object is directly proportional to the applied unbalanced force in the direction of force
3. Every action has an equal and opposite reaction
3 formulaes
1. v=u+at
2.s= ut+1/2at²
3.v²-u²+2as
