The idea that motion requires a force (push and pull) goes back to the 4th century BC when the Greeks we're developing scientific ideas.

Motion is an important thing to our lives and impacts us so many things we do.motion is the change in location or position.but motion requires a force to change locations.

Motion is observed by attaching a frame of reference to a body and measuring its change in position.

two kinds of motion : natural motion and unnatural motion.
Natural motion - motion that just happens
Unnatural- motion that happens with force

SOME MOTIONS THAT WE CAN CONTROL

• We pick up things
• We walk

The world is filled with motion .some motions just happen;the earth revolves around the sun ,snowflakes fall to the ground ,waves surge across the sea

In order to really understand motion is you have think about forces,acceleration energy,work,and mass.

Aristotle's theory of motion simply that everything is stationary or keeps on going until you give it a push for example imagine a ball on a very long table if we ignore friction and air resistance, the ball bearing will keep rolling until you stop it

he also figured out was that gravity is the glue to the earth that keeps us in motion
Think if you drop a pencil on the floor it goes to the center because the gravity keeps the pencil in motion.

Everything in the world is moving. Even things that seem still are in motion, because the atoms inside them are vibrating. An object moves from one place to another when forces act on it and those forces are not balanced.

Galileo is traditionally credited with being the first scientist to formalize the concept of inertia.

Galileo showed that objects of different weights fell to the ground at the same time

Galileo dropped a heavy object from the Leaning Tower of Pisa

Galileo demolished Aristotle’s ideas in the early 1500’s
Galileo showed that Aristotle was wrong about forces being necessary to keep objects moving

Inertia is the resistance of any physical object to any change in its state of motion, including changes to its speed and direction. It is the tendency of objects to keep moving in a straight line at constant velocity

The law of inertia states that it is the tendency of an object to resist a change in motion
