weight mass and gravity Flashcards
What is a gravitational force?
A gravitational force is a force of attraction between masses.
How does gravity effect objects?
Gravity makes objects fall towards the ground and gives everything a weight.
What is mass?
Mass is the amount of stuff in an object.
What is weight?
Weight is the force acting on an object due to gravity.
How does gravitational field strength vary?
Gravitational field strength is stronger the closer you are to the mass and stronger for larger masses.
What does the weight of an object depend on?
The weight of an object depends on the strength of gravitational field at the location.
What is weight measured in?
weight is measured in newtons (N).
Why is mass not a force?
mass is not a force as it is measured in kilograms with a mass balance.
What is the equation for weight?
weight = mass * gravitational field strength.
(N) (Kg) (N/Kg)
