5. ISSAC NEWTON (1642-1727)
• One of the greatest scientists
the world has known.
• Some most important and
famous discoveries and
inventions
o Gravity - Newton
o Laws of Motion.
o Calculus
o Reflecting Telescope

6. An apple fall from a tree
• Why the apple fell straight
down, rather than sideways
or even upward.?
• How did this explain why the
moon orbited the earth?
• What was the other force?

Gravitation

8. Newton’s universal law of gravitation
• Every particle in the universe attracts
every other particle with a force along
a line joining them.
• The force is directly proportional to
the product of their masses and
inversely proportional to the square
of the distance between them.
8

9. Equation
• F is the magnitude of gravitational force - N
• m1 and m2 are the masses of the objects – kg
• r is the distance between the centers of their masses - m
• G is the gravitational constant, equal to 6,673. 10−11

11. GRAVITY ACCELERATION
Newton’s universal law of gravitation
With: m is the mass of the object
M is the mass of Earth
r is the distance to the center
of Earth (earth radius)

Gravitational Constant Value
=> the force of gravitational attraction is only appreciable for objects
with large mass.
