1
Q
What is mass?
A
- Mass is the measure of the amount of matter an object contains.
- The mass of an object will never change.
- Mass is measured in kilograms
2
Q
What is weight?
A
- Weight is the measure of how hard gravity pulls down an object.
- The weight of an object can change.
- Weight is equal to a force
- Weight is measured in newtons.

Q
What is a dependent variable?
A
A dependent variable is a variable that will never change and is the base of an experiment.
4
Q
What is an independent variable?
A
An independent variable is a variable that can be changed and that helps conclude the results of the experiment.
