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.
It says that the mass of an object times its acceleration is equal to the sum of the forces acting on it. There are now two forces, gravity and air resistance. The force of gravity is the weight of the object: 9.8 * mass, directed downward. Air resistance can be handled in several ways; we choose the simplest. Assume the force of air resistance is proportional to velocity and in the opposite direction: k * velocity, where k is a negative constant. Differential Equation: Remember, mass * acceleration = gravity + air resistance. m*v'(t) = -9.8*m + k*v(t) In practice, k is determined by the size and shape of the object.
