An object that is IN motion tends to remain that way. Check out Newton's laws of thermodynamics. Basically, he postulated that things moving tend to keep moving, things stationary tend to stay stationary, and left to themselves, most thing degrade into chaos. This might sound silly, but you have to examine the statement a bit more. It's 'outside' forces, like gravity, friction, etc that act on objects to alter their movement or lack thereof. If you can imagine, for example a large glass bowl that has a vacuum inside it, and somehow, you could negate the force of gravity and friction as well. If you set a top spinning in the bowl, it would continue to spin forever - no friction to slow it down, no gravity to cause it to tip over, no air to cause drag, etc etc.
That tendency is called inertia. It is a property of matter where objects resist changes in their motion.
Inertia, the tendency of an object to keep moving in a straight line, combines with gravity, the force that pulls objects together, to cause orbiting. The inertia of an object causes it to keep moving forward, while gravity continuously pulls it towards the center of the orbit, creating a balance that results in a circular or elliptical path around another body.
It's Newton's first law of motion: "An oject in motion will stay in motion (with the same velocity) until an outside force acts upon it and an object at rest will stay at rest until an outside force acts upon it."
interia cant hold planets together. here is the definition for INERTIA: Inertia is the resistance of any physical object to a change in its state of motion or rest. It is represented numerically by an object's mass.Inertia is the resistance of any physical object to a change in its state of motion or rest. It is represented numerically by an object's mass.
Sir Isac Newtons first law of motion The law of inertia an object in motion remainsthe same unless acted upon by an external force.In space there is no force to slow itdown so it keeps moving the same speed it was when the rockets stopped burning.In other words:No force is required to keep a moving object moving, as long as there's nothing actingon it to make it stop.
An object's tendency to remain at rest or keep moving is measured by its inertia. Inertia is the resistance of an object to changes in its state of motion. The greater the inertia, the harder it is to change the object's state of rest or motion.
Interia is the tendency of a moving object to keep a moving in a straight line
Intertia is the tendency of an object to maintain its velocity: if an object is at rest, it has the tendency to remain at rest; if it is moving, the tendency is to keep moving with the same velocity. That is what happens if no forces act on the object; if forces act on the object, including gravitation, friction, and others, its velocity will change.
It is known as inertia, the tendency of an object to resist changes in its velocity. This means that an object in motion will continue moving at a constant speed in a straight line unless acted upon by an external force.
The tendency of a moving object to keep moving in a straight line after the kinetic energy has run out is due to inertia. Inertia is the property of matter that causes objects to resist changes in their motion, so an object in motion will continue moving at a constant velocity in a straight line unless acted upon by an external force.
The force that keeps an object moving is called inertia. This is the tendency of an object to resist changes in its velocity, either maintaining its current state of motion or remaining at rest.
That tendency is called inertia. It is an object's resistance to changes in its motion and is dependent on its mass.
The tendency of moving matter to keep moving in the same direction is known as inertia. Inertia is a property of matter where an object in motion tends to stay in motion unless acted upon by an external force. This concept is described by Newton's first law of motion.
Inertia
The natural tendency of a moving object is to keep moving. And it doesn't really require energy to stop it; in fact, in theory, you can gain energy from it. What is required is a force.
INERTIA. This is not an 'ability', but rather a PROPERTY of Matter.- Newtons First Law, "inertia", the propety of matter defined by a still object's tendency to stay at rest, and a moving object's tendency to keep moving at the same velocity.
The centripetal force required to keep an object moving in a circle increases as the velocity of the object increases. This is because a higher velocity means there is a greater tendency for the object to move in a straight line, requiring a stronger force to keep it moving in a circle. In other words, centripetal force is directly proportional to the square of the velocity of the object.
