Unit 1 – Kinematics (Motion)

• The rate of change of an object's position in a particular instant.

  Instantaneous Velocity
• The change in displacement over a certain period of time

  Average Velocity
• The change of displacement over time

  Velocity
• The change in distance over time

  Speed
• The rate change in velocity over a certain period of time

  Acceleration
• What is the change in speed each second for a freely falling body?

  9.81 m/s²
• How can an object accelerate while traveling at constant speed?

  As the direction the object is travelling in is changing, its velocity is also changing
• What is the acceleration of a rock thrown vertically upward when it reaches its highest point?

  9.81 m/s²
• Kinematics is concerned with...
