3 cards from this section. Quick, good the night before a test.
What is mass and how is it measured?
Think about how we measure our weight but for measuring matter.
What unit is weight measured in?
It relates to how much gravity pulls on an object.
How is mass defined?
What does mass represent in physics?
If an object has a weight of 50 N and its mass is 5 kg, what is the acceleration due to gravity used in this context?
Consider how to rearrange the weight formula.
A 70 kg astronaut travels to Mars where gravity is about 3.7 m/s². What would their weight be on Mars?
Use the same weight formula!
If an object has a mass of 120 kg and is on a planet where gravity is 8.5 m/s², what is its weight there?
Multiply mass by the provided gravity value.
