What is Volume?
Volume is the amount of space an object takes up.
100
What is the definition of weight?
Weight is the amount of force and object pushes down with.
100
What is the definition of gravity?
Gravity is the force that one object attracts another object with.
100
What is mass?
Mass is the amount of matter in an object.
100
What is Density?
Density is the amount of mass in a given amount of space, or how compact an object is.
200
What tool do we use to measure volume?
A Graduated Cylinder
200
What is acceleration?
Acceleration is the change in speed over a given amount of time.
200
How do you increase gravity?
Gravity increases as the mass of the object gets bigger
200
What is the tool that we use to find mass?
We use a scale.
200
What is the equation that we use to find density?
Density is Mass/ Volume
300
What units do we measure volume in?
mL and cm3
300
What are the two ways that you can increase the weight of an object?
You can increase the weight by adding mass or increasing gravity.
300
If you go to a planet with less mass, what will happen to the gravity of that planet?
The gravity will decrease.
300
What are the units attached to mass?
grams (g) or kilograms (kg)
300
What is the density of water?
1g/cm3
400
What are the steps to finding the volume of an irregular solid, and what is that process called?
Pour in water into a graduated cylinder Record Number Put irregular solid in graduated cylinder Record new volume Subtract the second volume from the first volume. The difference is volume of the object.
400
If you decrease the amount of mass an object has, what will happen to its weight? Why will this happen?
Its weight will decrease because it has less matter to push down with.
400
What are three objects in this room that have mass? List them in order from smallest to greatest.
Any 3 objects in the room
500
If I were to take my book to the moon where the gravity is less, what would happen to that object's weight? Why would that happen?
The weight will decrease because there is less force or gravity pushing down on the object.
500
How does Gravity affect mass, weight, and acceleration?
Mass- the more mass an object has, the stronger the gravity will be. Weight- the more gravity pushing on an object, the more weight an object will have. Acceleration: The more gravity, the higher the acceleration of an object will be.
500
How do change the mass of an object?
Increase or add matter to the object, or decrease or remove matter from the object.
