Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
Line integrals of vector fields in the plane Given the followingvector fields and oriented curves C, evaluate ∫C F ⋅ T ds.
Gravitational potential The potential function for the gravitational force field due to a mass M at the origin acting on a mass m is φ = GMm/ | r | , where r = ⟨x, y, z⟩ is the position vector of the mass m, and G is the gravitational constant.a. Compute the gravitational force field F = -∇φ .b. Show that the field is irrotational; that is, show that ∇ x F = 0.
Use Stoke's theorem to evaluate F.dr for the vector field F(x,y,z) = -3y2i+4zj+6xk; C is the triangle in the plane z=x/2 with vertices (2,0,0) , (0,-2,1) and (0,0,0) with anti-clockwise orientation looking down the positive z-axis.
