2. RECTILINEAR MOTION OF PARTICLE ◆ Rectilinear Motion In rectilinear motion, the particle moves along a straight line, which is considered to be the x axis. The kinematics of the motion is described as follows: The position of the particle is defined by the distance x between the particle and a fixed origin O on the straight line. The position x varies with the time during the motion, i.e., Where is a certain function of the time .

3. 1. The velocity(V) The instantaneous velocity of the particle ( its velocity at any instant ) is defined by the rate of change of its position with respect to the time, i.e., RECTILINEAR MOTION OF PARTICLE

4. 2. The Acceleration (a) It is defined as the time rate of change of the particle`s velocity, i.e., In some cases, as we will see later, it will be necessary to substitute the acceleration in the following mathematical form: Which is derived as follows: RECTILINEAR MOTION OF PARTICLE

6. 4. The Distance travelled (D) The distance travelled during a time interval is defined by the total length of the path over which the particle travels. RECTILINEAR MOTION OF PARTICLE

7. 4. The Distance travelled (D) The distance travelled during a time interval is defined by the total length of the path over which the particle travels. RECTILINEAR MOTION OF PARTICLE
