in my video it told how Galileo said that no force is needed to keep an object in uniform (a straight line)
it also said that forces change the motion of an object. Left them alone things would travel in a straight line forever. Its friction that slows them down.
Isaac Newton took Galileo's idea and summarized it as Newtons First Law.
"An object at rest tends to stay at rest. An object in motion tens to continue in motion at a constant speed in a straight line.
Newton's First Law- -It states that any object at rest stays at rest. -Any object in motion stays in motion at a constant speed in a straight line unless acted on by a external, unbalanced force. Examples: 1) It gives an example of a football sitting there, then someone comes up and kicks it giving it motion. 2) Then gives another example of a man pushing a grocery cart away from him. 3) It gives a demonstration about a car going fast in a straight line, then a big cloud gives it wind which causes it to slow down it speed. 4) Another example is a sailboat going at a constant speed, then wind comes behind it causing it to accelerate even more. 5) An example is when a airplane going in a straight line at a constant speed, then wind goes against it direction which causes the airplane to change its direction and velocity. 6) Another demonstration is when a soccer ball is going in a straight line, until someone makes contact with the ball.
Newtons first law is the law of inertia. It states an object at rest tends to remain at rest. An object in motion tends to remain in motion at constant velocity unless acted upon by an unbalanced force. An object remains at rest because the forces acting on it are balanced. Therefore velocity equals the change in position over the change in time.
The website I used provided many examples explaining the law of inertia it also stated the law then restated it in a way that other people could understand.
"Body at rest will remain at rest and a body in motion will remain in motion at a constant velocity.(constant speed in a straight line.) unless it is acted on by a net, external force."
It also has different interactive questions that you can answer to make sure that you understand the diiferent parts of the law.

An object at rest remains at rest, and an object in motion remains in motion unless acted upon unbalanced force. Unbalanced forces are forces with a net force other then zero. Unbalanced forces causes objects to accelerate. Acceleration is any change in velocity. For example When a ball is being kicked in a direction it moves in the same direction as forced is being applied to it. An other example of this first law is if you hammer a nail into a bored the force your hitting it makes the nail go threw the bored in witch the force your giving it to go in.
The website that I visited has a SWF file. It was a simple interactive game in which one could study Newton's laws, inertia, friction, and momentum. It has the terms listed on the left and an empty box on the right. When the cursor is placed over the terms, the definition appears in the box on the right. It is helpful and it was probably intended to be used as a study guide for the terms.
Newton's 1st Law: Every body continues in its state of rest, or of motion in a straight line at constant speed, unless it is compelled to change that state by a net force exerted upon it. In other words, an object that is acted upon by balanced forces, or no net force, will stay at rest (if initially at rest) or stay at constant velocity.
Newtons first law was that if a body is at rest it will remain at rest and if a body is in motion it will remain in motion. Example: If acceleration of a body is zero then there is no force upon it. Another great example was that if a rocket in a deep space accelerates up to a speed of 2.5 km/m and turns off its engine. How far does it travel in the next second. Well it travels 2.5 km/m
Newton's First Law-The name of the site is called Newton's Laws of Motion. The website first gives us some background on Newton. He was a classical physicist in the 17th century. He discovered gravity and he also made his own laws of motion. Laws that would later be refined by Kepler and then by Einstein. The site then defines Newtons first law. -Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. The site also states that Galileo first introduced the law, but called it Law of Inertia. It states force is only needed to start change velocity and to stop velocity. Forces include friction and gravity.
In this website it shows us all the basic stuff we have been learning like acceleration, velocity, constant speeds etc.
It states that Newtons first law is that an object at rest tends to remain at rest, and an object in motion tends to remain in motion at constant velocity(with the same speed and in the same direction) unless acted upon by an unbalanced force.
An object remains at rest because forces acting on it are balanced; not because there are NO forces acting upon it.
The velocity of an object remains unchanged unless acted upon by an unbalanced force or an object on will experience acceleration if acted upon by an unbalance force.
On this website it talks about newtons 1st law which stated that objects in motion wants to stay in motion and objects at rest want to stay at rest.
Some examples it gives are: Since the train is so huge, it is difficult to stop it once it is moving Since the baby carriage is so small, it is easy to move the baby from rest Since the soccer ball is so small, it is very easy to stop it once it is movi

This video has Newton's 1st, 2nd, and 3rd laws and explanations and some type of animation as an example.
-Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
Simply- motion will not change on its own. Needs to be pushed, pulled or stopped in some manner to change.

ReplyDeleteNewton's First Law
1)Newton’s first law of motion states that a body will stay at rest or move with constant velocity unless a resultant external force acts on it.
Example 1 a car parked at rest has the three forces (friction, weight and normal reaction
force) have zero resultant force.
Example 2 hoky puck
1. If a puck has an acceleration, then there must be a resultant force acting on it.
2. If a puck has no acceleration, then the forces acting on it must be in equilibrium (have zero
resultant force).
