Chapter 11 Review

Lengths are measured accurately using:

• rulers and tape measures

• estimation

• guesswork

• random selection

What is distance?

• A measure of how far apart objects are

• A type of speed

• A unit of time

• A form of energy

Displacement is:

• a vector quantity that refers to the change in position of an object.

• a scalar quantity that refers to the total path length traveled by an object.

• the rate of change of velocity of an object.

• the force exerted by an object due to gravity.

What is the displacement if you return to where you start?

• Zero

• Equal to the distance traveled

• Twice the distance traveled

• Cannot be determined

How do you find distance? How do you find displacement?

• By measuring the length of the path traveled and the shortest path between two points, respectively.

• By calculating the speed and time taken.

• By using a map and a compass.

• By estimating visually.

What is magnitude—how do you find it?

• Magnitude is the size or extent of something, and it can be found using mathematical formulas.

• Magnitude is a type of color, and it can be found using a color chart.

• Magnitude is a type of sound, and it can be found using a sound meter.

• Magnitude is a type of taste, and it can be found using a taste test.

What is the equation for speed (v)?

• v = d/t

• v = t/d

• v = d * t

• v = t * d

Where do you measure instantaneous speed?

• On a speedometer

• In a laboratory

• On a map

• In a textbook

How do you find average speed?

• By dividing total distance by total time

• By multiplying total distance by total time

• By adding total distance and total time

• By subtracting total time from total distance

What does a slope represent on a graph? How do you compare speed using slopes?

• A slope represents the rate of change on a graph; steeper slopes indicate faster speeds.

• A slope represents the highest point on a graph; steeper slopes indicate slower speeds.

• A slope represents the lowest point on a graph; steeper slopes indicate constant speeds.

• A slope represents the average value on a graph; steeper slopes indicate variable speeds.
