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.

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:
