Question	Answer
The amount of matter in an object independent of its size or any forces acting on it defines which term?	Mass
The tendency of an object to remain at rest or remain in motion with the same speed and same direction and is measured by its mass defines which term?	Inertia
The force of gravity on an object defines which term?	Weight
A force acting on an object from the outside as opposed to forces acting within the object define which term?	External force
The net force which is the vector sum of all external forces defines which term?	Net force
What symbol is used for gravitational field strength (acceleration)?	g
What symbol is used for force due to gravity?	Fg
G=9.8m/s² is acceleration due to gravity	True
Weight is another word for force due to gravity	True
The weight of an object is the force due to gravity on the object and may be defined as the mass times the acceleration of gravity	True
Since weight is a force what unit is this represented by?	Newtons
Mass m= Force N (weight) / acceleration of gravity	True
What is the value of acceleration of gravity (g)?	9.8m/s
The forces are balanced defines which term?	Equilibrium
The amount of force that would give a 1kg mass an acceleration of 1m/s2 defines which term?	Newton
Acceleration is the net force divided by mass of an object	True
1N = 1kgm/s2	True
Force = mass x acceleration	True
