Gravity Flashcards
what Is meant by the term mass
mass is a measurement of the amount of matter an object has
does the mass of an object change
the mass of an object never changes
what is the equation for weight
Weight = Mass x Gravitational Field Strength
what apparatus’ can be used to measure weight
1) Calibrated spring balance
2) digital balance
what is meant by the term weight
force that acts on the object when it is in a gravitational field
weight is equal to what
Weight is equal to mass multiplied by the gravitational field strength
what is meant by the term centre of mass
where all of the mass appears to be
when are the two scenarios In which an object will fall over
1) An object will fall over if its centre of mass is outside its base.
2) An object will fall off a surface if its centre of mass isn’t over the surface.
what is weight measured in
weight is measured in newtons
