Mass is measure of inertia.
Inertia is ability of a body to maintain constant velocity.
In oder to increase velocity of 1kg particle by 1m/s the force of 1Newton must be applied for 1 second.
In oder to increase velocity of 2kg particle by 1m/s the force of 2Newton must be applied for 1 second.
The latter particle has twice the mass.
As particle approaches the speed of light, accerating it further becomes more and more difficult. Becuase it cannot exceed the speed of light. If the particle is aready only 0.5m/s slower than the speed of light, no amount of force will add extra 1m/s to its current velocity. You can add, say, 0.25 m/s and make it move only 0.25m/s slower than c, but the force applied to the body will be enormous. Thus fast moving particle has huge inertia, and therefore huge apparent mass.
Warning:
Do not try to derive equation from this explanation, the equation will be wrong. Read the real textbooks instead.

before everything, you seem puzzled on the adaptation between mass and weight. Mass is the quantity of rely that an merchandise has while weight is the tension that a mass exerts interior the presence of a gravitational pull. In relativity, there is the in call for equation E=MC(squared). This tells us that power has mass, in uncomplicated terms an exceptionally tiny volume of it. So while your speed gets as much as amazingly extreme speeds, the flexibility of this speed has a lots larger mass than at low speeds. because of the fact the speed will develop, the mass of the flexibility in touch additionally will develop. As on your final fact "the bigger the mass the slower it strikes", that's based on the belief of momentum. Momentum = mass * speed. in case you develop the mass of an merchandise with out increasing it rather is power of speed, then it is going to look after a similar momentum, and would flow at a slower value. So, the two are outstanding in a manner, it relies upon on while you're conversing approximately increasing the fee, or increasing the mass. increasing the fee will develop the flexibility, which will develop the mass (despite the fact that it does not decelerate because of the fact we are increasing the fee). If we are in uncomplicated terms increasing the mass with out increasing the fee, the speed will drop to maintain a similar power because of the fact the flexibility has no longer been replaced.

as one approaches the speed of light, the the mass of the objects remains constant. instead its momentum increases without limit.
p=gamma*mv as v approaches c, gamma approaches infinity. mass remains constant.
its a bad idea to think rest mass*gamma = relativistic mass.
while this equation works for the simplest cases, it doesn't always, and its physically wrong. instead think in ways of momentum.
