What is the magnitude of vector a? || a || = 3 Magnitude is a scalar, or a number that does not indicate direction.Ī. Magnitude of a vector is written: || x ||. Observe : The magnitude of a vector is the distance from the vector’s initial point to its terminal point. Question: How can you determine a vector’s magnitude and angle? You will need a scientific calculator for this activity.Change vector a so that its notation is 0 i + 3 j.Drag the terminal point of a so that it lines up with the y -axis. Which componentĭescribes the vector’s position along the x -axis? iĬ. Drag the terminal point of vector a so that it lines up with the x -axis. How did the components of vector a change? No change occurred.ī. Move the initial point of vector a to the origin (0, 0) on the grid.Ī. What is the unit vector notation of vector a? The two components written together make up the unit vector notation. Each vector is described by twoĬomponents : the i component and the j component. The initial point ofĮach vector is shown with a circle. Look at vectors a and b on the Vectors Gizmo grid. The plane will still move forwards but since there is a gust of wind coming fromĭisplacement, velocity, momentum, acceleration, and force are allĮxamples of quantities that have both direction and magnitude.Īnything with direction and magnitude can be represented using a Prior Knowledge Question (Do this BEFORE using the Gizmo.)
