4 days ago · Newton's laws of motion are three physical laws that describe the relationship between the motion of an object and the forces acting on it. These laws, which provide the basis for Newtonian mechanics, can be paraphrased as follows: A body remains at rest, or in motion at a constant speed in a straight line, except insofar as it is acted upon by ...

The equations of motion of kinematics describe the most fundamental concepts of motion of an object. These equations govern the motion of an object in 1D, 2D and 3D. They can easily be used to calculate expressions such as the position, velocity, or acceleration of an object at various times.

May 10, 2024 · The next several examples consider the motion of the subway train shown in Figure 3.3. In (a), the shuttle moves to the right, and in (b), it moves to the left. The examples are designed to further illustrate aspects of motion and to illustrate some of the reasoning that goes into solving problems.

May 21, 2024 · Kinematics of uniform circular motion. We know from kinematics that acceleration is a change in velocity, either in its magnitude or in its direction, or both. In a uniform circular motion, the direction of the velocity changes constantly, so there is always an associated acceleration, even though the magnitude of the velocity might be constant.
