science fair project

2. 
Newton: the SI unit of force. It is equal to the force that would
give a mass of one kilogram an acceleration of one meter
per second.

Gravity: the force that attracts a body toward the center of
the earth, or toward any other physical body having mass.
For most purposes Newton's laws of gravity apply.

Fundamental: forming a necessary base or core.

4. 
Pendulum Balls represent 3 main principals of
physics.

Conservation of Energy

Conservation of Momentum

Friction

5. Conservation of momentum:
a principle stating that energy cannot be
created or destroyed, but can be altered
from one form to another.
 Conservation of Energy:
the principle that the total momentum
that is constant and is not changes.
 Friction:
the resistance that one surface or object
encounters when moving over another.


6. 
Pendulum balls look like a simple toy when
placed on a desk, but it really represent the
basic fundamentals of physics shown in the
slide before.

These balls can also be called the following:

Kinetic Balls, Newton Balls, Balance Balls
and Newton's Pendulum.

7. Here is an example of a similar gravitational
pull as the pendulum balls:
Think about a glass bowl sitting on a table
and the bowl weighs 5 N. The bowls weight
is the measurement of Earths gravitational
attraction.
If the bowl weighs 5 N, Earth is applying
a force of 5 N to the bowl. The force is
directed down, toward the center of the
earth. But the bowl stays motionless. This
means that there must be another force
that is equal to 5 N, that is pushing up which
is the force coming from the table.

8. The materials needed is pendulum balls
and a ruler.
 The first thing you do is swing the ball and
then measure the slope which is the
height of the ball.
 The next thing you have to do is find out
how the 3 main principals of physics
work.
