Weight is the force of gravity pulling on a mass and is?

• 1 kg = 10N (9.81N)

• 10 kg = 10N (9.81N)

• 100 kg = 10N (9.81N)

• 0.1 kg = 10N (9.81N)

Weight is a force, it is measured in?

• KG

• Newtons

• Grams

• Pounds

To find the density of an object, use the following formula

• density = mass / volume

• volume = mass / density

• density = mass + volume

• density = mass - volume

Relative density is when we compare the mass of material. Water has a relative density of?

• 1

• 2

• 0.1

• 10
