3 cards from this section. Quick, good the night before a test.
What is the SI unit of mass?
It is the standard unit used to measure the amount of matter.
What is the formula for calculating weight?
Remember W stands for weight, m for mass, and g for the acceleration due to gravity.
What is the SI unit of weight?
Think about the force of gravity in the metric system.
True or False: Mass changes depending on where you are in the universe.
Recall that mass measures the amount of matter.
An astronaut has a mass of 70 kg on Earth. Calculate their weight on Earth, then on the Moon where g = 1.6 m/s². How does this illustrate the difference between weight and mass?
Use the formula W = mg for both calculations.
You have a 10 kg mass that weighs differently in different locations. If its weight is measured as 98 N on Earth, what would be its weight on Mars where g = 3.7 m/s²?
Apply the weight formula W = mg, substituting the new g for Mars.
