speed=distance/time
Average Speed= Total distance travelled/ Total time taken
Average velocity= initial velocity + final velocity / 2
Mathematically, average velocity= u+ v/ 2
u= initial velocity
v= final velocity
Average Velocity = Displacement/ Total time taken
force and law of motion.
Force = mass× acceleration
⭕ First equation of motion.
= v=u+ at
⭕ Second equation of motion
= s=ut+1/2 at^2
⭕ Third equation of motion
= v^2=u^2 +2as
where u = initial Velocity of object.
v= final Velocity of object.
a= acceleration.
t= time.
Gravitation
⭕ Universal law of Gravitation.
let ,
Mass of two objects = m1 and m2.
Distance between the two objects = do.
Force of attraction acting between them = F.
It will be given by the Universal law of Gravitation.
F = G m1m2/d^2
where Value of G is the universal constant.
and G=6.66×10^-11Nm^2kg^2
⭕ Magnitude of the gravitational force.
Mass of the Earth =M_E
Mass of an object on its surface =m.
Radius of the Earth = R
According to the universal law of Gravitation, t he gravitational force (f) acting between the earth and the object is given by the relation:
F=aGm1m2/r^2
Thus, the formula will be,
F=GM_E m/R^2.
