4 -Newtons Laws of Motion
Force is the action (push or
pull) that tends to change
the state of motion of an
object.
An object at rest needs a
force to get it moving; a
moving object needs a
force to change its
velocity
When several forces act on an objec

Motion in One Dimension
What is motion?
Motion is the continuous change in the
position of an object.
What are the different types of motion?
Three types:
1.
Translational motion e.g.
2.
Rotational motion e.g. the motion of earth about its axis

Linear Momentum and Collisions
Linear Momentum
The linear momentum of a particle, or an
object that can be modeled as a particle, of
mass m moving with a velocity v is defined to
be the product of the mass and velocity:
p = mv

Angular Momentum
In mechanics, a rigid body is defined as a system of particles whose relative
distances remain constant. This means that the body does not change its shape
during its motion.
A rigid body undergoes translation

Elasticity
1. Introduction
It is possible to change the shape or size of an object or both by applying external forces.
The material that is deformed always resists the deformation by internal reaction forces.
The internal reaction forces that resist th

The Vector Product
There are instances where the product of two
vectors is another vector
Earlier we saw where the product of two vectors
was a scalar
This was called the dot product
The vector product of two vectors is also

Work and energy
The work W done by an agent exerting a constant force is defined as the product of
the component of the force along the direction of displacement and the magnitude of
the displacement.
W = (F cos ) s = F.s

Motion in Two Dimensions
To study the motion of a particle in two dimensions (e.g. xy plane) we begin by defining its
position by a position vector r drawn from the origin of x-y coordinates system to the
location of the particle as shown in fig
