An introduction to motion

2. Within the scope of
the study of motion
are many different
concepts.

3. Displacement
While distance and displacement are commonly
used interchangeably, it is important to note that
displacement is a vector quantity that describes a
change in position as illustrated by the
Pythagorean theorem.

4. Velocity
• When a position changes in a certain amount
of time we have motion.
• The rate of that change is called velocity.
• It is represented by the equation v=d/t.

5. Acceleration
• When an object's
velocity changes, the
rate of that change is
acceleration.
• Acceleration is
represented by the
equation: a=v/t

6. Motion in two
dimensions
• Objects in motion rarely
move in one or two
dimensions.
• For introductory physics we
will consider motion in two
dimensions.

7. Two dimensional
motion examples:
Trajectories or ballistic motion

8. Two dimensional
motion examples:
Rotation- complex enough to study separately

9. Equations for two dimensional
motion with acceleration
• Each equation the student to
one unknown.
• Equations can be solved
simultaneously to solve for
two unknowns.

10. Relative motion
Often, things change position with respect to time and
another moving object. This is the principle of relative
motion.
