The mass of an object depends on how much matter it contains.
Newton's second Law states that an object's acceleration is proportional to the resultant force acting on it.
The relationship can be represented by the equation:
F = m a
where F is the resultant force, m is the mass and a is the acceleration.
One newton is the force that will give a mass of 1kg an acceleration of 1 ms-2.
The weight of an object on the surface of the Earth is the gravitational force acting on that object.
W = m g
W = weight, m = mass, g = gravitational field strength.
The instrument for measuring force is the newtonmeter.
Mass was considered a constant until the special theory of relativity in 1905. The mass of a particle depends on its speed according to the equation
m = m0/√(1 - (v/c)2)
where m0 is the rest mass of the object and c is the speed of light.
