This presentation covers the topics of forces, types of forces, balanced and unbalanced forces, and Newton's laws of motion. It defines a force as a push or pull and describes several types of forces including gravitational, electrical, air resistance, and normal forces. It explains that balanced forces result in no change in motion, while unbalanced forces cause acceleration. Newton's three laws of motion are also summarized, including that an object at rest stays at rest unless acted on by an unbalanced force, acceleration is directly proportional to net force, and for every action there is an equal and opposite reaction.

1. FORCES & MOTION

2. THIS PRESENTATION WILL COVER
 WHAT IS FORCE
 TYPES OF FORCES
 BALANCED AND UNBALANCED FORCES
 NEWTON’S LAW OF MOTION

3. . Forces

4. A force is simply a push or a
pull.
•All forces have both size and
direction
OR

6. Air resistance force
What is air resistance?
Basically, it is friction between an
object and the air.
What causes air resistance?
All matter is made from atoms
and/or molecules. The air is no
exception. When something
moves through the air, it bumps
into the atoms and molecules

10. Gravitational force
Newton’s fiery of gravitational forces :
“Every particle of matter in the universe attracts
every other particle with a
force that is directly proportional to the
product of the masses of the
particles and inversely proportional to
the square of the distance between
them.”

11. Electrical force
What is electrical force?
The attractive or repulsive
interaction between any two
charged objects is an electric
force. Like any force, its
affect upon objects.

12. Normal force
What is normal force?

14. Balanced vs. unbalanced forces
• BALANCED
• UNBALANCED

15. BALANCED: WHEN THE NET FORCE ON AN OBJECT
EQUALS ZERO. THESE DO NOT PRODUCE CHANGE IN
MOTION.

16. UNBALANCED
: WHEN THE
NET FORCE
ON AN
OBJECT IS
NOT ZERO.
THESE
PRODUCE A
CHANGE IN
MOTION.

17. WHAT IS MOTION?
WHEN AN OBJECT
CHANGES POSITION OVER
TIME WHEN COMPARED
WITH A REFERENCE POINT
WE SAY THAT THE OBJECT
IS IN MOTION.

18. ISAAC NEWTON IS WELL KNOWN FOR HIS
DISCOVERIES IN OPTICS (WHITE LIGHT
COMPOSITION) AND MATHEMATICS
(CALCULUS), IT IS HIS FORMULATION OF
THE THREELAWSOFMOTION—THEBASIC
PRINCIPLESOF MODERNPHYSICS—FOR
WHICH HE IS MOST FAMOUS.

19. Newton’s 1st
Law
An object at rest remains at
rest and an object in motion will
continue moving at a constant
velocity unless acted on by
unbalanced forces.

20. NEWTON'S SECOND LAW:
IF AN UNBALANCED FORCE ACTS ON AN
OBJECT, IT WILL CAUSE IT TO ACCELERATE,
WHERE ACCELERATION IS DIRECTLY
PROPORTIANL TO THE NET FORCE.

21. NEWTON'S THIRD LAW:
EVERY FORCE CREATES AN EQUAL FORCE
IN THE OPPOSITE DIRECTION.
The hammer
exerts a force on
the nail to the
right.
The nail exerts
an equal but
opposite force
on the hammer
to the left.
