Example 1. A constant force acting on a body of mass 3.0 kg changes its speed from 2.0 m/s to 3.5m/s in 25 s. The direction of the motion of the body does not changes. What is the magnitude and what is the direction of the force? Solution. Mass of the body, m = 3 kg. Initial speed of body, u = 2 m/s.

Formula for Force. The quantity of force is expressed by the vector product of mass (m) and acceleration (a). The equation or the formula for force can mathematically be expressed in the form of:
Newton's Laws: Forces and Motion. A force is a push or a pull. A force is a vector : it has a magnitude and a direction. Forces add like vectors, not like scalars. Example: Two forces, labeled. same magnitude. F1 and F2, are both acting on the same object. The forces have the.

The SI unit of force is called the newton (abbreviated N), and 1 N is the force needed to accelerate an object with a mass of 1 kg at a rate of 1 m/s 2: 1 N = 1 kg • m/s 2. An easy way to remember the size of a newton is to imagine holding a small apple; it has a weight of about 1 N.
