Describe Displacement:

• The total distance traveled by an object.

• The change in position of an object in a specific direction.

• The speed of an object.

• The force applied to an object.

Rules for adding Displacements:

• Add the magnitudes of all displacements.

• Subtract the magnitudes of all displacements.

• Add the magnitudes of displacements in the same direction and subtract those in opposite directions.

• Multiply the magnitudes of all displacements.

A deer runs 14 m north, 6 m south, then 3 m north. What is the total displacement?

• 11 m north

• 23 m north

• 5 m north

• 17 m north

Describe speed:

• The distance traveled per unit of time.

• The change in position of an object in a specific direction.

• The force applied to an object.

• The total distance traveled by an object.

Speed Equation:

• Speed = Distance / Time

• Speed = Time / Distance

• Speed = Distance x Time

• Speed = Distance + Time

A car traveling at a constant speed covers a distance of 750 m in 25 s. What is the car's speed?

• 30 m/s

• 25 m/s

• 15 m/s

• 10 m/s

Identify 2 common ways of expressing a changing speed.

Describe Velocity:

• The speed of an object in a specific direction.

• The total distance traveled by an object.

• The force applied to an object.

• The change in position of an object over time.

How are speed and velocity different?

• Speed includes direction, velocity does not.

• Velocity includes direction, speed does not.

• Speed is a vector quantity, velocity is not.

• Speed and velocity are the same.
