Newton's second law states that the speed of acceleration of a moving object depends on the object's mass and the force being exerted on it. One instance of this is the understanding that it requires much more force to push a vehicle than to kick a soccer ball, for example.
Know MoreSimply, Newton's second law represents the fact that the greater the mass of an object, the more force there is needed in order to move it. This explains why, for example, it requires one person to easily lift a box weighing five pounds but multiple people exerting more force collectively to lift a box weighing 100 pounds. Acceleration, or the speed of a moving object, can be calculated with the equation Acceleration = Force / Mass.

Full Answer >Newton’s second law states that the force acting on an object is directly related to the acceleration. The law is formulated as F = m x a, where F = force, a = acceleration and m = mass of the object in motion. In terms of Atwood’s machine, a force equal to the difference in the suspended weights accelerates the total mass, m1+ m2.
Full Answer >The amount of matter in an object is referred to as its mass. Although the mass of an object is one of the factors that determines its weight, it is a different property. An object's weight is affected by gravity and can vary depending upon its location relevant to another object exerting a gravitational pull on it; however, an object's mass remains constant, even when there is no gravity acting upon it, such as in space beyond the Earth's gravitational field.
Full Answer >Electrons have a relative mass of 9.1 x 10^-31 kilograms, or 0.51 megaelectron volts. They are a lot smaller than protons and neutrons; and, an electron is roughly 0.054 percent of the mass of one neutron.
