So what…
The Framing RoutineThe first main topic is…
Distance and Displacement
What are some
important details
about this topic?
• Distance is a measure of how far something has traveled.
• Displacement is measure of how far something is from its original starting position.
• Units for distance and displacement are…
• Distance is a scalar quantity…which means that a direction IS NOT necessary.
Meters… Kilometers… Feet… Miles…
• Displacement is a vector quantity…which means that a direction IS necessary.

Speed and Velocity
What are some
important details
about this topic?
• Speed is measure of the distance traveled in a given amount of time.
• Speed is a rate or how fast something is moving. • Speed is a scalar quantity…no direction is
necessary.
• Velocity is a vector quantity…a direction is necessary.
• Velocity is measure of the displacement in a given amount of time.
• If motion is in a single direction, the terms speed and velocity are often used interchangeably.

Acceleration and Gravity
What are some
important details
about this topic?
• Acceleration is the rate at which velocity changes.
• Acceleration is a vector quantity…direction is important.
• When an object increases velocity, it accelerates.
• When an object decreases velocity, it decelerates.
• Units for acceleration are…
Meters/second2… feet/second2…
• The acceleration due to gravity is called “g”.
• The value of g on Earth is…9.8 m/s2 or 32ft/s2.

What are some
important details
about this topic?
• When an object is only being acted on by gravity, it is said to be in free-fall.
• In the absence of gravity, all objects are accelerated at the same rate.
• Equations that relate distance, velocity, and acceleration include:
