Arizona State University| PHY 121: Univ Physics I: Mechanics|Homework 1-1| Problem 4| Finding the Acceleration Vector
Learning Goal: To practice finding the acceleration vector
Suppose an object has an initial velocity at time and later, at time , has velocity . The fact that the velocity changes tells us the object undergoes an acceleration during the time interval . 116 more words

To practice Tactics Box 1.2 Vector Subtraction.
Vector subtraction has some similarities to the subtraction of two scalar quantities. With numbers, subtraction is the same as the addition of a negative number. 155 more words
To practice Tactics Box 1.1 Vector Addition.
Vector addition obeys rules that are different from those for the addition of two scalar quantities. When you add two vectors, their directions, as well as their magnitudes, must be taken into account. 124 more words
