you 'll hear the terms , balanced forces and unbalanced forces a lot when you 're dealing with physics and what i wan na do in this video is give you a bunch of scenarios and have you think about whether the forces in these scenarios are balanced or unbalanced . so let 's start with the scenario where we have the groun...
and you do have two forces that are counteracting on the horizontal direction . this guy 's pushing harder with 3 n , but the force of friction is now 2 n to the left . so you do have a net force to the right .
wo n't the force of friction also play a part when the second guy ( in the last scenario ) is pushing ?

you 'll hear the terms , balanced forces and unbalanced forces a lot when you 're dealing with physics and what i wan na do in this video is give you a bunch of scenarios and have you think about whether the forces in these scenarios are balanced or unbalanced . so let 's start with the scenario where we have the groun...
and now he 's pushing with a force of 3 n to the right and the force of friction is still 2 n to the left . so that right over there is the force of friction . now let 's do a couple of more scenarios .

we 're sitting on the ground in the vertical direction , normal force counteracting the force of gravity . those are balanced . but in the horizontal direction .
this may sound silly , but if two forces are balanced why does a object move at a constant velocity instead of being stationary ?

let 's draw another scenario where i have a rock now . maybe the same rock . and here i have a 5 n force downwards .
the person 's hand does not go in the rock because the rock pushes him back with equal force , right ?

we 're assuming we 're not going to think too much about -- actually let 's think about it a little bit , let 's also put , so let 's put it ... so i have the force of gravity . that 's 5 n down . but i have some air resistance here . you can view it as the force of friction of the air , and let 's say that is 1 n up .
if air resistance was 5 what would happen then ?

so we have some character here and he 's trying to push the rock and he 's applying a force of 2 n to the right . but then there 's a force of friction between the rock and the ground that is going 2 ... i 'll do friction in orange 2 n to the left so that right over there is the force of friction .
in the 4th scenario would'nt the force of friction also help the fist person by going againdt the second person ?

but then the rock is being supported by the ground , the ground is keeping it from being plummeted downward . so the ground is providing an upwards force or normal force in this situation . the ground is providing a normal force , i 'll do it in green .
do the force of friction remains same for an object on a given ground ?

and you do have two forces that are counteracting on the horizontal direction . this guy 's pushing harder with 3 n , but the force of friction is now 2 n to the left . so you do have a net force to the right .
like let 's say although friction at it 's peak is 2n , and the guy is pushing at a force of 1n , would friction also be 1n ?

we would not consider this one of the scenarios we see an unbalanced force . let 's go to scenario 2 . once again , 5 n up and 5 n down , they are balancing each other .
and does the same go for gravity ?

we should talk a little more about newtons 's third law , because there are some deep misconceptions that many people have about this law . it seems simple , but it 's not nearly as simple as you might think . so people often phrase it as , for every action there 's an equal and opposite reaction . but that 's just wa...

whether it 's hitting a wall , sitting on a table , falling through space , these two forces must always be equal and opposite , because of the third law . so how about this other force , this force that the table was exerting . so this is , the force on a by the table .
it seems to me that there is more going on than just the wall exerting a force ... why is it only exerting this force at the instant when chuck norris comes into contact with it ?

that does not look like the correct form for a drop kick . but even if i came in , flying at this wall , as soon as i start to make contact with the wall , i 'm gon na exert a force on the wall , and the wall has to exert a force back . so i 'd exert a force on the wall to the right .
also ... why does the wall break ?

so it has to be an upward force . and that upward force has to be exerted on the earth , by box a , and this is kind of weird , because you may not have realized it , but if the earth is pulling down on a box , or you , that means you are pulling up on the earth . and this might seem ridiculous , i mean if you jump up ...
does it mean that the box is pulling the earth with somekind of gravitationnal field ?

in other words , the forces could be equal , but the accelerations do n't have to be equal . acceleration is gon na be the net force divided by the mass . so even if the force is the same , you divide by that mass , you 'll get a different acceleration and that 's why the result of the force does not have to be the sam...
also , is there a presence of a net force hence the upward acceleration ?

as soon as your foot starts to exert any force on the wall what so ever , the wall is gon na start exerting that same force back on your foot . so newtons 's third law is universal , but people still have trouble identifying these third law partner forces . so one of the best ways to do it , is by listing both objects ...
does the law apply in non inertial frames ?
