The last few days in the science class we have been learning about motion. Motion is the process of changing position. To understand more of motion we did a test with the balloon on a string, message transportation vehicle.

What is motion? Motion, in general, is the
process of changing position or location. Motion comes in different forms and
ways. For example when we release the balloon, it move fast and it turn around
the straw while getting smaller. The position begins to change when we release
the air in the balloon and move because
of the force in the balloon.
We measure motion with speed, velocity or
acceleration. The way we measure speed and velocity are very similar. The
formula for velocity is v=d/t. You can measure the speed of motion by use this
formula, s=d/t. For example the distance of the string is 3.5 and one of our
times is 1.25 so it is S=3.5/1.25. S is equally to 2.8, the speed of the motion
is 2.8 . When I was researching I found out that momentum is a quality of
motion of a moving body, measured as a product of mass.
Forces are things that make motion move or
happen. Without force there is no motion. There are 2 different forces, balance
and unbalance force. Balance force is when both side are the same
size but pulling at opposite direction. For example, during tug of war both
side must have the same amount of people and begin pulling at opposite direction.
Unbalance force is when both sides are not the same size but pulling at the
opposite direction. For example, during tug of war one side have larger amount
of people than the other side and begin pulling at opposite direction.
