Concepts of biomechanic

What is biomechanics?

Is the science of studying living things from a mechanical perspective

Concepts of biomechanic


General motion: To bowl the

ball, the rotation of the shoulder,

elbow and wrist is needed all of this

different types of movements is

called general motion.

Concepts of biomechanic

Linear motion:

movement of the

body where all parts move in the same

direction at the same time along a line.

Angular motion

movement of a body part around an axis of rotation.

Concepts of biomechanic

Linear Motion:

Distance and Displacement:

Distance: the path travelled by a body from point A to B

Displacement: change of position of a body.

An example is a; netball player who weaves, dodges, baulks and then sprints forward to receive the ball may cover 15 metres altogether = 15 metres travelled by netball player. So it doesn’t matter how much she ran it matters where she started n finished

Concepts of biomechanic

Projectile motion:

What it is: anything ( including a human body) that is launched in to the air and only effected by gravity.

Vertical and horizontal components:

Anything launched into the air that can be considered a projectile will have horizontal and vertical components. An example is if you drop one ball and throw another ball from the same height at the same time, they will both hit the ground at the same time because they have the vertical of motion.

Concepts of biomechanic


When buoyancy force and weight are equal an object will float,but when weight of an object is greater than the buoyancy force, it willsink.

Drag force:

The effect of streamline. (@) A ball is not very streamline so there is great drag created behind the ball as it travels. (B) A teardrop-shaped bicycle helmet is very streamlined, which reduces the amount of drag created behind it

Concepts of biomechanic


  • A sport that requires very little or sudden movements and a lot of concentration

Mass And Weight:

Mass: the amount of matter that makes up an object.

Weight: the measure of gravity force on a body.

Concepts of biomechanic


push or a pull acting

on an object in sporting

situations it is very easy

to see when a force is acting


Angular motion is

caused by a force

that does not act

through the centre

of gravity of an object.

Concepts of biomechanic

Speed And Velocity:

Distance (length of the path a body follows) and displacement (length of a straight line joining the start and finish points) are quantities used to describe a body's motion. e.g. in a 400m race on a 400m track the distance is 400 metres but their displacement will be zero metres (start and finish at the same point).


An example is, while a body is in the air it is force to a downward acceleration because of gravity.

Concepts of biomechanic

Types Of Forces

There are a number of different external forces that act on the body like gravity, weight, friction and air and water resistance


Friction that acts in the opposite direction of motion when two surfaces are in contact with one another.

Concepts of biomechanic


Momentum is a measure of the amount of motion that an object has. The amount of momentum an object has in directly related to its mass and its velocity.


Impulse is equal to the change in momentum of an object. To change the momentum of an object, a force must applied over a period of time. Impulse is equal to the force applied multiplied by the of the force application:

Impulse= force × time

Concepts of biomechanic


A collision between two objects is known as impact. In sport, the impact occurs between a ball and another contact surface such as a bat, body part or ground surface. The type of collision that occurs determines the motion of the ball after impact.
