Year 9 Physics Unit 1 Length, volume and density

What is the equation for density

• Mass/Volume

• Volume/Mass

• Weight

• mass * Volume

Volume is __________.

• how many atoms
• how much matter is in an object
• how  much something weighs

Matter is anything that has

• length width and hieght
• anything that has mas and volume
• a definite shape
• energy

What causes an object to float in a water?

• if the object's density is less than the water's density.
• if the object's density is the same as the water's density
• if the object's density is greater than the water's density
• if the object's density is zero

What are the 3 states of matter?

• ice rock and desk 
• solid liquid and gas 
• matter volume density
• hard soft medium

What causes an object to sink in a water?

• if the object's density is less than the water's density.
• if the object's density is the same as water's density.
• if the object's density is greater than water's density.
• if the object's density is zero
