Motion
- Involves movement or a change in the position of a thing or a body.
- You need the energy to move
- Change in position concerning a frame of reference or reference point.
- Change in position for a particular time interval

Tbxbypes of Motion
A. Vibratory Motion
- Movement of things that are vibrating
Ex: Rubber band, speakers
B. Rectilinear Motion
- Motion along a straight line/ straight path
Ex: A runner running in a straight track
C. Curvilinear motion
- Motion along a curved path
Ex: When you shoot a basketball into a hoop.
D. Oscillatory Motion
- Movement that is happening repeated
E Circular Motion
- Motion along a circular path
Ex: Satelite around the earth
F. Rotatory Motion
- Movement along a Fixed Axis
Ex: A ceiling fan 

Reference Point
- Starting point or the origin for measuring motion.

Mechanics
- The study of an object's state of motion and the forces acting upon it.

Two types of Mechanics
Kinematics
- deals with the description of motion without regard to the forces acting on the object.

Dynamics
- is concerned with how the state of motion is affected by the forces acting upon the object


Scalars & Vectors

Scalars
- Has magnitude only
- Examples of Scalar quantities are Distance, mass, temperature, time, length, area, volume, mass, density, pressure, energy, entropy, work, power, and speed.
Ex: 20m/s
Vectors
- Has magnitude and direction
- Examples of Vector quantities are Velocity, displacement, acceleration, momentum, force, lift, drag, and thrust.
Ex: 20m/s, right
