100
What is the purpose of scientific notation?
To make either very large or very small numbers manageable.
100
Convert 1 kilogram to grams.
1000 grams.
100
What is the metric measurement used for length?
Meters
100
An object has a mass of 1000 grams and a volume of 100 milliliters. What is its density?
10 g/mL
100
What is the name of the downward force constantly applied to everything on earth?
Gravity.
200
Convert this number to scientific notation: 723,000,000,000
7.23 x 10e11
200
Convert 1500 milliliters to liters.
1.5 liters.
200
Define the concept of volume.
The amount of space an object takes up.
200
Would an object with a density of 9.01 g/cme3 float or sink in water?
It would sink because the density of water is around 1 g/cm3.
200
What is the term used for speed in a given direction?
Velocity.
300
Convert this number to scientific notation: 102,040,000,000,000
1.0204 x 10e14
300
Convert 462,000,000 cm to km.
4620 km
300
Define the concept of mass.
How much matter is in an object.
300
Define the concept of density.
The amount of mass contained in a given unit of volume.
300
This term describes the rate of change in velocity.
Acceleration.
400
Convert this number to standard notation: 2.385 x 10e14
238,500,000,000,000
400
What are the three most common metric units of measurement for mass?
Kilograms, grams, and milligrams.
400
Does an object still have mass in a zero gravity environment?
Yes. Mass is not solely defined by gravity's effect.
400
Define Buoyancy and Archimedes' Principle.
Buoyancy is the force water exerts upward on an object within it. Archimedes' Principle states that the force exerted is equal to the weight of the water being displaced.
400
The tendency for an object in motion to stay in motion due to its mass and velocity is called _________.
Momentum.
500
Convert this number to scientific notation .000000000064
6.4 x 10e-11
500
Explain why converting numbers in the metric system is as easy as swinging the decimal over a few places.
Each increase or decrease in measurement is a change of 10x. Something that is 10x more always moves the decimal right once. Something that is 10x less always moves the decimal left. 100x would be two spots, 1000 would be three spots etc.
500
How would you find the volume of a square room? What about an irregularly shaped object?
length x width x height. An irregular shaped object could be measured by observing the volume change when submerged in a pre-measured container of water.
500
Using Archimedes' Principle, explain how a submarine operates.
A submarine is able to manipulate its own density. By taking in water it is able to increase its weight past the amount of the water being displaced thus defeating the buoyancy. By releasing the water and taking in air it can become lighter than the weight of the water being displaced and thus float.

A baseball player hits a 120 km/h fastball with a force of 11,642 newtons. What was the force of the ball hitting the bat?
11,642 newtons.
