Physics Right Hand Rule Vector Product

The vector product of a and b is always perpendicular to both a and b. For that we need the right hand rule. Using the right hand rule to find the direction of the cross product of two vectors in the plane of the page.

The right hand rule is a visualization technique used to determine the correct direction of a vector resulting from vector cross product multiplication.

Physics right hand rule vector product. Make sure it s not your left or it won t work. It is based on the following sign convention for an xyz coordinate system as shown below. This allows some easy calculations using the vector cross product. The direction of the vector product can be visualized with the right hand rule.

D left the right hand rule used to find the direction of e a b and right the right hand rule used to find the direction of e b a. Hold your index finger middle finger. C left a cos θ is the component of a along b and right b cos θ is the component of b along a. If you curl the fingers of your right hand so that they follow a rotation from vector a to vector b then the thumb will point in the direction of the vector product.

To use the right hand rule you first have to hold up your right hand. B the vector difference a b a b d. The length of the vector gives the speed of rotation and the direction of the axis gives the direction of rotation according to the right hand rule. Right fingers curled in the direction of rotation and the right thumb pointing in the positive direction of the axis.

Right hand rule vector product. A the vector sum c a b b a.
