Ch1, Lesson 1 - Science Study Guide

Magnetism is a force that

• only pulls on other objects

• pushes and pulls on other objects

• pulls all objects toward Earth's center

• is always greatest between a magnet's two poles

What is the best way to determine if an apple as more mass than a baseball?

• Place a magnet next to each object and see which attracts

• use a pan balance and the one with more mass will move lower

• give each object an equal push

• look at the size of each object

If 2 objects balance each other on a pan balance, what can you conclude?

• One has a greater volume than the other

• they have the same mass

• one has a greater mass than the other

• they have the same volume

If you place a coin in a cup of water and it sank to the bottom, what can you conclude about density?

• the density of the coin is less than the water

• the density of the water is 1 gram per cubic cm

• the water and coin have the same density

• the density of the coin is greater than the water

Which is best tool to use if you were gathering information to compare three rocks?

• a beaker

• a graduated cylinder

• a pan balance

• none of the above

What is the connection to an object's density and it's ability to float or sink?

• an object will float if its density is greater

• an object will float if its density is less

• an object will sink if its density is less

• an object will sink if its density is half

How can you compare two objects' masses by pushing them?

• the object with less mass will move a shorter distance

• the object with less mass will not move

• the object with more mass will move the farthest

• the object with less mass will move farther or faster

What do you know about particles that make up a hot substance?

• particles are moving very slowly

• the particles are cold and bounce around

• the particles are moving very quickly

• the particles are staying at the bottom

THe mass of an object divided by its volume is its

• volume

• mass

• matter

• density

The amount of matter in a solid, liquid or gas is

• density

• mass

• volume

• magnetism
