4. INTRODUCTION
• Momentum is a property of a moving body that the
body has by virtue of its mass and motion and that
is equal to the product of the body's mass and
velocity.
• It could also be referred to as a property of a
moving body that determines the length of time
required to bring it to rest when under the action of
a constant force or moment.
• It is a strength or force gained by motion or by a
series of events.

9. THEORY BEHIND MOMENTUM
• Momentum is a conserved quantity (it cannot be created nor destroyed),
meaning that the total momentum of any closed system (one not affected by
external forces, and whose internal forces are not lost) cannot be changed.

10. THEORY BEHIND MOMENTUM CONTD.
• In general, the momentum of an object can be thought of, as how difficult it
is to stop the object. This is determined by multiplying two factors: the
mass of the object and its velocity. It means, having a lower speed or
having less mass (how we measure inertia) results in having less
momentum.
• The concept of momentum in classical mechanics was originated by a
number of great thinkers and experimentalists. René Descartes referred to
mass times velocity as the fundamental force of motion. Galileo in his Two
New Sciences used the term "impeto" (Italian), while Newton's Laws of
Motion uses motus (Latin), which has been interpreted by subsequent
scholars to mean momentum.

11. MOMENTUM EXPLAINED
• Momentum is the product of the mass of a particle and its velocity.
Momentum is a vector quantity; that is, it has both magnitude and
direction.
• Isaac Newton’s second law of motion states that the time rate of change
of momentum is equal to the force acting on the particle.
• From Newton’s second law it follows that, if a constant force acts on a
particle for a given time, the product of force and the time interval (the
impulse) is equal to the change in the momentum.
• Conversely, the momentum of a particle is a measure of the time required
for a constant force to bring it to rest.

13. MOMENTUM EXPLAINED CONTD.

• According to Newton’s Third law, the particles exert equal and
opposite forces on one another, so any change in the
momentum of one particle is exactly balanced by an equal
and opposite change of the momentum of another particle.
• Thus, in the absence of a net external force acting on a
collection of particles, their total momentum never changes;
this is the meaning of the Law of Conservation of Momentum.

14. FORMULA FOR MOMENTUM
Momentum 14
• Momentum = Mass x Velocity
• The S.I unit of momentum is kilogram meter per second (kg-m/s)
or Newton second (Ns).
• This means that a boy of mass 20 kg and runs at a speed of 30 m/s
is carrying a momentum of 600 kg-m/s or 600Ns.
