what is galileo laws of inertia?
Answers
Explanation:
Galileo's law of inertia states: If a body going up moves slower and slower, and a body going down goes faster and faster, a body that neither going up nor going down goes neither slower nor faster; it goes with a constant speed along the same straight line.
Galileo and Inertia

Inertia is the tendency of matter to resist changes in its velocity.
Inertia is a property of matter. It is that property of matter which opposes changes in velocity.
Simply stated, a common object will not change its velocity spontaneously.
If something is moving along at a constant speed in a straight line, it will continue to move along at the same constant speed in the same straight line. It will not, all on its own, speed up, slow down, or change direction. Something else must push on the object to speed it up, slow it down, or change its direction.
Also, if something is standing still, it will, if left to itself, continue to stand still. Something else must push on an object to get it moving. Actually, an object standing still is just a special case of an object keeping its velocity constant. Its velocity is constantly 0 m/s.
You could get a much more comprehensive answer by simply googleing the question, but as long as we're on the subject. An object at rest tends to stay at rest, an object in motion tends to stay in motion unless acted upon by an outside force. Now, the object in motion has velocity and mass. The inertial force only becomes apparent when the outside force is applied to the velocity. After Einstein we learned that inertia and gravity are the same force soyou're standing on earth is: acceleration toward the earth acted upon by the outside force of the ground. You can have acceleration without velocity and velocity without acceleration.
Galileo's law of inertia is another name for newton's First. law of motion
Newton's first law states that an object will remain at rest or move at a constant speed in a straight line unless it is acted on by an unbalanced force. Inertia comes from mass. Objects with more mass have more inertia.
