For objects that fall to earth from a distance of several feet or meters, the effect of air resistance can usually be neglected. To simplify the discussion of gravity, we will just ignore air resistance for now. ...

... A force is a push or pull that acts on an object. * A force can cause a resting object to move * A force can accelerate an object by changing its speed or direction. * Force is measured in Newtons. A Newton is the force that causes a 1-kilogram mass to accelerate at a rate of 1 m/s2. 1 N = 1kg*m/s2 ...
