What is the equation for force?

Answer 1

By definition, force F is the rate of change of momentum p.

Thus, F = dp/dt

Now, momentum is the product of mass m and velocity v.

If mass is constant,

F = m x dv/dt

F = ma (a = dv/dt)

where a is acceleration.

Now if velocity is constant but mass is changing,

F = v dm/dt.

Force is also equal to the product of pressure and area.

Answer 2

F=k(q1q2/r2)
d is the distance between particles
q1 represents the quantity of charge of one particle
q2 represents the quantitiy of charge of another particle
k is the proportionality constant; k=9 000 000 000 N.m2/C2
or it can be expressed as k=9.0X10^9

Answer 3

Force is the space derivative of energy, thus electromagnetic energy is hf=hc/r force is:

F = [d/dr, Del] hc/r = [-hc/r2 , -hc/r2 1R] = -hc/r2 [1,1R]= -p/t [1,1R]

The electromagnetic force is a Quaternion force consisting of a scalar force and a vector force.

Answer 4

F=M x A

Force = Mass (x) Acceleration

Answer 5

F=ma

F=force

m=mass

a=acceleration

Answer 6

emf = I(R+r) = IR + Ir = V + Ir

Answer 7

Force = Mass * Acceleration

Answer 8

Force = (mass) times (acceleration)

Answer 9

V=ke(q/r)
