|
Kinetics |
The branch of dynamic concerned with the forces that cause or tend to cause motion. |
|
|
Kinematics |
The branch of dynamics concerned with the description of motion |
|
|
Statics |
The branch of rigid-body mechanics concerned with the mechanics of objects at rest or moving at constant velocity. |
|
|
Dynamics |
Branch of r-body mechanics concerned with the accelerated motion of objects. |
|
|
Inertia |
The resistance of any physical object to any change in its state of motion, including changes to its speed and direction. It is the tendency of objects to keep moving in a straight line at constant velocity. |
|
|
Power |
Rate of doing work; work done divided by time; measured in units of work divided by units of time or expressed as watts in SI; a scalar quantity. |
|
|
Weight |
Measure of the force of gravity acting on an object; mass times the acceleration due to gravity; expressed as newtons in SI. |
|
|
Coefficient of Restitution |
Ratio of the velocity of separation to the velocity of approach between two colliding objects abbreviated as e. |
|
|
Biomechanics |
The study of forces and their effects on living systems. |
|
|
Impulse |
Average force times the duration of application of the force; causes and thus equal to change in linear momentum; measured in units of force times units of time or expressed as newton seconds in SI; a vector quantity. |
|
|
Momentum |
the property or tendency of a moving object to continue moving. |
|
|
Vector |
Mathematical representation of any quantity that is defined by its size or magnitude and its direction. |
|
|
Scalar |
Quantities described fully by its magnitude (or numerical value) |
|
|
Friction |
The component of a contact force that acts parallel to the surface in contact |
|
|
work |
The product of force exerted on an object times the displacement of the object at the point of application of the force along the line of action of the force. |
|
|
energy |
the capacity to do work; expressed as units of force times units of length or as joules |
|
|
displacement |
change in location of a point expressed as the length and direction of the vector from the starting position to the ending position |
|
|
velocity |
the rate and direction of the change in the position of an object |
|
|
acceleration |
Vector quantity that is defined as the rate at which an object changes its velocity. |
