SUMMATIVE TEST-Speed and Velocity 4/25

What is the definition of "average" in the context of data?

• Occurring immediately

• The sum of all items in a data set divided by the total number of items

• The steepness of a line on a graph

What does "instantaneous" mean?

• A displacement per unit of time

• Occurring immediately

• The distance traveled per unit of time

What is a "position vs time graph" used for?

• To show the relationship between the position of an object over time

• To calculate the steepness of a line

How is "slope" defined in the context of a graph?

• The distance traveled per unit of time

• The steepness of a line on a graph

What is the definition of "velocity"?

• The distance traveled per unit of time

• A displacement per unit of time; or distance traveled per unit of time in a specific direction

• The sum of all items in a data set divided by the total number of items

What is the definition of "speed"?

• A displacement per unit of time

• The distance traveled per unit of time

• The steepness of a line on a graph

What is needed to determine distance or displacement?

• Speed

• Reference point

• Time

Which two measurements are needed to determine speed?

• Distance and time

• Displacement and direction

• Force and energy

What does average speed include?

• Total distance and total time

• Displacement and direction

• Force and acceleration

What is velocity defined as in physics?

• The displacement of an object during a specific unit of time

• The distance traveled by an object

• The force applied to an object
