velocity = speed + direction of motion Things that have both a magnitude and a direction are called vectors. More on vectors in Ch.3. For 1D motion (motion along a straight line, like on an air track), we can represent the direction of motion with a +/– sign. + = going right .

Step 1: Draw free-body diagram showing forces (show direction of acceleration off to one side of diagram.) Step 2: Choose a coordinate system and a + direction (always best to choose the direction of the acceleration as the +direction) Step 3: Write down equations F . a , F y m a y.
• Examples of motion in one dimension: – Displacement, velocity, acceleration, free fall, and …. In a straight line. • An example of motion in two dimension (x and y axis) is projectile motion. • An example of a three dimensional motion (x, y and z axis) is motion of a bird or an insect since it is flying in space. 12 CMPE department-TIU
