The document discusses different types of forces including gravitational, magnetic, nuclear, and muscular forces. Gravitational force causes objects to pull on each other and keeps planets orbiting the sun. Magnetic force is exerted between magnets and metallic substances. Nuclear force binds quarks together inside protons and neutrons in atomic nuclei with a power 100 times greater than electromagnetic force. Muscular force allows animals to push and pull objects.

1. TYPES OF FORCES

2. We are surrounded by a variety of
moving objects in our day –to-day
lives. Cars , buses, airplanes, boats
and animals are examples of
moving objects.
An object that is moving is said to be in
motion.

3. TYPES OF FORCES

Fundamental
Forces.

4. What makes
the ball
Move?
The man
pushes the
ball with his
racket.
What makes the car
move? The man pushes
the car.
What makes the wagon
move? The child pulls the
wagon.
In the above pictures the objects are being moved by a
push or a pull.
A push or a pull acting on objects is called a force.

5. Gravitational force
Gravitational force is the force with which objects
pull one another.
It is the gravitational force that keeps us bound to
the earth.
It also makes the Earth and other planets revolve
around the sun.

6. Magnetic force is the force exerted by magnets on
each other and metallic substances.

7. The nuclear force keeps together the most basic of elementary
particles, the quarks. The quarks combine together to form the
protons and neutrons in an atomic nucleus. They power of the nuclear
force is 100 times that of electromagnetic force. This pulls together
the quarks and forces them to fuse. It is also used in machines which
require tremendous power to work like submarines and atom bombs.

8. It is the type of force which animals use to
push or pull things.
