What’s happening here? Has mass changed? Has weight changed? Why?

Weight is the force due to gravity which pulls you down to the ground, measured in Newtons

Mass is how much of an object there is and is measured in Kg

* Forces and MassKeywords:Force (N)Mass (kg)Weight (N)FrictionForce diagrams

weight (N) = mass (kg) x gravity

Gravity is about 10 on Earth
