10/18 do now The mass of a space shuttle is approximately 2.0 × 10 6 kg. During lift-off, the net force on the shuttle is 1.0 × 10 7 newtons directed upward.
The magnitude (speed)of a vector quantity is represented by the size of the vector arrow. If the size of the arrow in each vector diagram is the same,

Adding Vectors Graphically CCHS Physics. Vectors and Scalars Scalar has only magnitude Vector has both magnitude and direction –Arrows are used to represent.
Motion Speed: average and instantaneous Velocity Acceleration.
Force: An action exerted on an object (a push or a pull) in order to change the state of rest or motion of an object. Measured in Newtons (N)
