Today, Gigabytes and Terabytes are the most common terms being used to describe the size of a hard drive. But what are they? This is where it gets quite confusing because there are at least three accepted definitions of each term.
A force acting on an object can cause it to accelerate. The relationship between force, mass and acceleration is given by the equation. force = mass Ã acceleration. The stopping distance of a car depends on two factors-thinking distance and braking distance. Under normal driving conditions, the thinking and braking distance depend on the speed of the car.
Now the units of force per mass are also those of acceleration. And it so happens that because gravitational mass (the thing that feels gravity) is equivalent to inertial mass (the m in Newton's second law that resists acceleration), the m's cancel if gravity is the only force acting. F = ma = mg, so a=g.
