# Physics – Newton’s First Law of Motion

Imagine you’re sitting on a recliner chair watching your favorite movie on a lazy Sunday And your mom calls out your name and asks you to run some errands You can imagine how [difficult] it would be for you to get up and do the work imagine you’re practicing for your 100 meters race on this track and Somebody asks you to stop immediately within a second Will you be able to do it? What if you suddenly ask to turn towards the right? Will you be able to turn immediately? The answer to both the questions would [be] a [no] You can stop yes, but gradually you can also turn But not sharply and guess what it’s the same story with every object every Object will continue to do what it’s doing if it’s at rest It will remain at rest and if it’s in motion it will stay in motion But what can change this? yes only an unbalanced Force can change this if It’s at Risk and an unbalanced [Force] acts on it It will move if it’s in constant motion and an unbalanced Force acts on it it May accelerate or change Direction and This is nothing, but the Newton’s first law of motion cheers the correct definition an Object at rest stays at rest and an object in motion stays in motion with the same speed and the same [direction] unless acted upon by an unbalanced Force [in] Simple words it means that the objects continue to do what they’re doing unless some external unbalanced force acts on them we can also understand this using a simple diagram if the Forces are balanced there can be two cases an Object may be at rest [or] an object will be in motion at a Nonzero constant velocity in a particular Direction These can be the only two cases when the forces are balanced in the first case the object will continue to remain at rest and In the second the object will continue to stay in motion [as] the same velocity and in the same direction Don’t forget these two [cases] will remain true. Only if the forces are balanced in The next video we will look at a few applications of the first law of motion

Yup, another way of seeing it is imagining objects as lazy. Those objects won't move if not "touched" and won't stop if not "touched" again with the same amount of force (and opposite direction) because they are lazy and want to continue doing what they are doing (moving or not moving).

After all this first law is also called the inertia principle and inertia in latin means indolent. Just an easy way of remembering the lesson (I think).

thank you

Awesome video! Thanks because I am doing laws of motion at school and this helps me to understand better!
Great effort!!

These videos are amazing!!! I watched all 3 Law of Newton video and went to class and was not lost.. but only with the math part so that is what I will be working on this weekend. But other than that… I like the simple videos more. Great Job!

please make a video on "time relativity"!!!!;!!!!!!!!!!

When it stands same velocity and same direction I believe it is wrong because velocity is speed with direction

Big fan

Can an example be a train moving at a fast speed. Then it will stop slowly as the brakes are used( the brakes are the unbalanced force)

• ### Grema Fernandes Post author

beautifully shortly explained wonderful

Yes I can turn while running or stop mid way. Sure it takes practise, but itβs not impossible.

Iβm sorry but you are saying that if I kick a bal it wil keep rolling til something wil stop it but the bal wil de accelerate after some time so ur not explaining it right

Esto es El translation Imagine you're sitting on a recliner chair watching your favorite movie on a lazy sunday and your mom calls out your name and asks you to do some errands. You can imagine how difficult it would be for you to get up and do the work. Imagine you are practicing for your 100 meters race on this track and somebody asks you to stop immediately within a second will you be able to do it?
What if you suddenly ask to turn towards the right? Will you be able to turn immediately? The answer to both the questions would be a no. You can stop yes, but gradually you can also turn but not sharply and guess what it is the same story with every object every object will continue to do what it is doing if it is at rest it will remain at rest and if it is in motion it will stay in motion. But what can change this? Only an unbalanced force can change this if its at rest and an unbalanced force acts on it, it will move if it is in constant motion and an unbalanced acts on it, it may accelerate and change direction. This is nothing but Newton's first law of motion, cheers the correct definition an object at rest stays at rest and an object in motion stays in motion with the same speed and the same direction unless acted upon by an unbalanced for. In simple words, it means that the objects continue to do what they're doing unless some external unbalanced force acts on them. We can also understand this using a simple diagram. If the forces are balanced there can be 2 cases an object may be at rest or an object will be in motion at a nonzero constant velocity in a particular direction. These can be the only 2 cases when the force are balanced in the first case the object will continue to remain at rest and in the second, the object will continue to stay in motion as the same velocity and in the same direction. This remains true if the forces are balanced. This concludes the information about Newton's first law of motion

Hello to grade eight 2019 here

• ### shakesphere Pulga Post author

I think its wrong newtons 1st law is an object stay at the rest until it formed an unbalanced force

• ### shakesphere Pulga Post author

If theres no unbalanced force the ball just rolling in a floor theres no unbalanced in the floor that the ball will keep rolling but if its applied with an unbalanced force the ball will stop rolling thats the newtons 1st law
