1
Q
What is mass and what is weight?
A
Mass - Amount of matter (kg)
Weight - FORCE exerted by a mass due to gravity (N - Newtons)
2
Q
What is the unit for mass?
A
Kilograms (kg)
3
Q
What effects the strength of gravity?
A
1) Mass of object
2) Distance of object (i.e. G.F.S.)
4
Q
What is the equation for weight?
A
Weight (N) = Mass (kg) x Gravitational Field Strength (N/Kg)
5
Q
What is the weight of a object of 25Kg mass on Earth?
A
Weight = Mass x G.F.S. Weight = 25 Kg x 10 N/Kg Weight = 250N
