This document discusses different types of forces. It begins by explaining that moving objects are said to be in motion. It then states that a push or pull acting on an object is called a force. The document goes on to list and briefly describe four main types of forces: gravitational force, magnetic force, nuclear force, and muscular force.

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. 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.

4. TYPES OF FORCES
1. Gravitational Force
2. Magnetic Force
3. Nuclear Force
4. Muscular Force
Fundamental
Forces.

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.

9. 1. An object that is moving is said to be in motion.
2. A push or pull acting on an object is called force.
3. The 4 types of forces are gravitational force, muscular, nuclear and magnetic
