physical science chapter 6 review

A physical measurement that contains only magnitude (number) and does not contain directional information

• reference point

• displacement

• vector quantity

• scalar quantity

The time rate of change of an object's velocity

• average speed

• instantaneous speed

• velocity

• acceleration

A point at which direction is measured

• reference point

• displacement

• vector

• scalar

The rate at which an object is moving at a given moment in time

• average speed

• instantaneous speed

• average velocity

• acceleration

The distance an object travels plus the direction from the starting point

• reference point

• displacement

• acceleration

• velocity

A physical measurement that contains both magnitude (number) and directional information

• reference point

• displacement

• vector quantity

• scalar quantity

The ratio of the total distance traveled to the total time of the trip

• average speed

• instantaneous speed

• acceleration

• displacement

If you are a passenger in the rear seat of a car moving at a stead speed, relative to whom are you at rest

• a person on the side of the road

• a pedestrian on the corner

• the driver in the front seat

• a person in a passing car

You walk 1 mile every day for exercise, leaving your front door at 9:00 AM and returning to your front door at 9:25 AM. What is the total displacement of your daily walk

• 0 miles

• 1 miles

• 2 miles

• none of these

you are looking in a scientist's lab notebook and find the following unlabeled measurements: 12.1 m/s

What physical quantity was the scientist measuring

• acceleration

• displacement

• speed

• velocity
