Dynamics |
Branch of Mechanics which deals with the study of bodies in motion |
|
|
Motion |
One of the properties of bodies It was pointed out that the force has a tendency to produce motion or change of motion |
|
|
Kinematics |
Study of motion |
|
|
Translation (Rectilinear Motio) |
Is a motion of a body in a straight line The body does not rotate, the motion will be referred to the center of mass coincides with the center of gravity |
|
|
Displacement |
Change of position of a body |
|
|
1. A falling body 2. A sliding body in a plane 3. Train traveling on a straight track |
Examples of motion translation |
|
|
1. Uniform motion 2. Variable motion 3. Uniformly accelerated motion |
Types of translation motion |
|
|
Uniform motion (uniform translational motion) |
One with a constant velocity, must necessarily be straight line motion |
|
|
Variable motion |
Different distances traveled, equal times |
|
|
Uniformly accelerated motion |
Velocity is not constant but increases or decreases by a uniform rate |
|
|
Deceleration or retardation |
Negative acceleration |
|
|
Acceleration |
Rate of change of velocity |
