The best way to get deeper into this is to solve a few concrete problems with given movement and mass of an object and the forces acting upon it. Since the horizontal component is adjacent to the angle that we're given, we're gonna write the horizontal component as the magnitude of the total vector 20 meters per second times cosine of the angle, which gives us 10 meters per second. The greater the mass - the less deviation from the trajectory would be observed. The degree of deviation depends on the strength and direction of the resulting force and the mass of an object. If the resulting force acts at an angle to a trajectory of an object, it will deviate from that trajectory. For two-dimensional motion, the path of an object can be represented with three vectors: one vector shows the straight-line path between the initial and final. If the resulting force directed against the movement, the object will decelerate. If, for example, the resulting force directed along the way the object is moving, it will continue moving along the same trajectory, but accelerating on its way. The absolute value of the acceleration depends on the magnitude of the resulting force and the mass of an object.

The resulting force is the source of acceleration of an object towards the direction of this force. To determine the result of forces acting on an object at any moment we have, first of all, add forces together according to the rules of adding the vectors (the rule of parallelogram).

The change depends on the strength and directions of forces and on the way the object moved before forces acted upon it. Determine components of a vector along two specified, mutually perpendicular.

Forces acting on any object change its movement. Motion in two dimensions, including projectile motion.
