Gravitational Force
Gravitatuional Force
F = ?
gravitional force of attraction acting form the centre of mass of the two objects
Gravitional force
G=
Gravitional constant = 6.67* 10-11 Nm2Kg2
Gravitional force
m1 =
Gravitional force
= mass of one of the objects (kg)
Gravitional force
m2 =
= mass of the other object (kg)
Gravitional force
r=
= distance between the centre of mass of the two objects (m)
Calculating the weight force (aka Gravitational force)
F = m xg
weight force
F = ?
wight force
= gravitational force or weight on an object
measured in newtons (N)
weight force
m =
wright force
= mass of object
measured in Kg
weight force
g =
weight force
= gravitational field strength = 9.8 N/kg on and near the surface of the Earth
Electrostatic force formula (Coulombs Law)
Electrostatic force (coulombs law)
F = ?
k=?
q1=?
q2 =?
r = ?
Electrostatic force (coulombs law)
F = electrostratic force acting between two charged objects (N)
k = coulombs constant = 9.0* 109 Nm2 C-2
q1= magitude of one of the charged objects (C)
q2 = magnitude of the other charged object
r = distance between the centre of the two charges (m)
Newtons 2nd law of motion
newtons second law of motion
ΣF=?
m=?
a=?
newtons second law of motion
ΣF= net force acting on object (N)
m=mass of object (kg)
a= accerlation of object (m/s2)
Constant accerlation formulae:
V=?
s=?
s=?
s=?
v2=?
Constant accerlation formulae:
v=u + at
s = ut + 0.5at2
s= vt - 0.5at2
s= ((u+v) x t)/2
v2= u2 + 2as
