Biomechanics is the scientific study of the mechanics of biological systems, focusing on the forces acting on the human body and their effects. It is divided into two main branches: kinematics, which deals with the description of motion without regard to forces, and kinetics, which examines the forces causing motion. Additionally, biomechanics explores concepts such as linear and angular motion, each identified by the direction and nature of movement.

2. What is biomechanics
• Bio means life
• Mechanics means science
concerned with the forces
and the effect of these
forces on the body

3. What is Biomechanics
• It is a scientific study
of the mechanics of
biological system
• It is a study of structure
and function of biological
systems by the use of
means and methods of
mechanics. Hatze H,1974

4. What is biomechanics
• Biomechanics is the science concerned with
the internal and external forces acting on a
human body and the effects produced by
these forces

6. What is Mechanics
• It is a branch of physics concerned with
the action of forces on the bodies,
• Mechanics has two major division, statics
and Dynamics
• Static : The study of forces acting
to produce equilibrium
• Dynamic : The study of forces
acting to produce motion. Dynamic
is further subdivided into the two
area of the study, kinematics and
kinetics

7. Kinematic
• Kinematics : It is concerned with the
description of movements in time and
space. Example, displacement, velocity,
and acceleration without regards to the
forces that bring about the action

8. Kinetics
• Kinetics : It is concerned with the
forces that cause motions, not with
the description of movements.
• Example : muscular contraction,
gravity, momentum

11. Dynamics
Kinetics

12. Kinetics
Inertia
Mass
Weight
Force
Power
Pressure
Momentum
Work
Newton’s law
Impulse
Couple of force
Moment of inertia
Lever
Angular momentum

13. What is Linear
• Linear means in a
straight line.
• Object moves in linear
motion means , object
and its all particles
moves in same direction
for same distance, in a
straight line from one
point to other point.
• Example : 100 mtrs
sprint. Approach run in
Javelin ets.

14. What is Angular
• Angular means movement take
place in angle rather than straight
line.
• Movements take place around a fix
axes, in a curvature path, so all part
of the body move through the same
angle, in same time and in same
direction.
• The travelled distance from initial
point is measure in a angle
• Example : golf etc
