What is a force?
A push or a pull that
one body exerts on
another.

3. PUSHING PULLING

4. EXAMPLESOFFORCE
• Fingers open a book.
• Push buttons on keyboard.
• Gravity holds up a chair.
• Two magnets coming together.
VISIBLE FORCES
INVISIBLE FORCES

5. ORIGINOFFORCE
• Forces are due to an interaction. An
interaction of one object results force
between the two objects.

6. Newtons
• It is represented by the ‘F’.
• Force is measured by S.I units.
• S.I units of force is NEWTON.
• Therefore, 1N = 1 kg • m
s2

7. TYPESOF FORCES

8. •Contact forces
•Non- contact forces
•Electrostatic forces
•Gravitational forces

9. CONTACTFORCES
• Contact forces are those that cause
change in another object because the
objects are physically touching one
another.
• This type of force is also known as
MUSCULAR FORCES.
• Example: pull the baby

10. NON-CONTACTFORCES
• A non- contact force occurs when the
forces acts from the distance.
• Example: magnet

11. ELECTROSTATICFORCES
• The force exerted by a charged body
on another charged body is known as
electrostatic forces.
• example: rubbing a comb on hair
attract pieces of paper.

12. GRAVITATIONAL FORCES
• The objects or things falls
towards the earth because
gravity pulls them downward
is known as gravitational
forces.
• This is also known as
newton’s law of gravitation.
• Example: apple falling from
tree
