The DIRECTION tells you where the vector is pointing. Prepared by Vince Zaccone For Campus Learning Assistance Services at UCSB Here’s a typical example: An airplane is flying East at a velocity of 600 kilometers per hour. Here the magnitude (speed) is 600 km/hr and the direction is East. A diagram of this vector might look like this: V= 600 km/hr Normally vectors will be written in BOLDFACE or with an arrow above the letter: V = 600 km/hr East or V =600 km/hr East Notice that the diagram above has a nonbold V – this means magnitude. So V=600 km/hr describes the magnitude of V . You might also see this as  V  = 600 km/hr. The absolute value bars indicate magnitude. Prepared by Vince Zaccone For Campus Learning Assistance Services at UCSB Let’s try a quick example with our airplane. Suppose that while this plane is flying 600 km/hr East, it then encounters a wind blowing North at 100 km/hr. How does this affect the VELOCITY of the airplane? Prepared by Vince Zaccone For Campus Learning Assistance Services at UCSB Let’s try a quick example with our airplane. Suppose that while this plane is flying 600 km/hr East, it then encounters a wind blowing North at 100 km/hr. How does this affect the VELOCITY of the airplane? The plane gets blown off course, of course. We need to find the new VELOCITY. Like any vector, it will have a MAGNITUDE (speed) and a DIRECTION Here is a diagram: 100 km/hr 600 km/hr Prepared by Vince Zaccone For Campus Learning Assistance Services at UCSB Let’s try a quick example with our airplane.

Like any vector, it will have a MAGNITUDE (speed) and a DIRECTION Here is a diagram: So how do we find the new SPEED of the plane? Answer: Add the vectors together Is the new speed just 600 km/hr +100 km/hr = 700 km/hr?...
