### Why body starts moving when force is applied? [duplicate]

The recent question by m.buettner regarding self-inductance and its resistance to EMF Faraday's law - does the induced current's magnetic field affect the change in flux?, recalled me the ...

### How is the horse able to pull the cart? [duplicate]

To me, the horse's role is merely to transmit the force it is being pushed forward with by the ground over to the cart. So, let's say, the ground pushes horse with 20 N, the horse pulls cart with 20 N,...

### Force balancing - Newtonian mechanics [duplicate]

If a horse pulls the carriage, the carriage should pull the horse with equal force (Newton's third law), then how does the whole system move? I drew the free body diagram but not yet figured what ...

### How is acceleration in cars possible? [duplicate]

Based on the understanding that Newtons third law states for every action there is an equal and opposite reaction, when a car moves forward under driving force, air resistance and friction act equally ...

### Why does Newton's Third Law not preclude any motion at all? [duplicate]

When walking, if I apply a force of 2N on the earth, the earth applies a force of 2N back on my feet due to Newtons 3rd Law of Motion. These 2 forces are equal in magnitude but opposite in direction, ...

### Newton's third law. how things can move? [duplicate]

I am beginner in physics and i have some questions about Newton's third law The law says : When one body exerts a force on a second body, the second body simultaneously exerts a force equal in ...

### Why don't the two forces balance each other In Newton 3rd law? [duplicate]

Why don't the two forces of action and reaction balance each other ? I imagine that although they are opposite forces, they have different points of application. Is this true?

### Action and reaction forces during collision [duplicate]

How can the action and reaction force be same.? And if so then how the colliding objects could further move as there net force is Zero. Since F1 = - F2, that means that the force act on both sides ...

### Newton's third law, why does this body move? [duplicate]

while i have tried reading explanations for why newtons third law doesn't mean objects can't move such as this one: With Newton's third law, why are things capable of moving? I still do not ...

### Surface friction and Newton's third law [duplicate]

My question is regarding a specific case displaying Newton's third law. In the diagram below, a man is shown exerting a force on the wall, which in turn causes an equal and opposite reaction force ...

### Elastic behaviour of objects [duplicate]

If I strike my car with a wrench with enough force to make a dent in it, then it's obvious that I won't be able to produce any acceleration in the car. But I am applying an external deforming force. ...

### How does Newton's 3rd Law apply to arm wrestling? [duplicate]

I understand that when we refer to Newton's third law, forces do not cancel out because action-reaction pair forces are acting on different objects. I tried to apply this to arm wrestling, but I am a ...

### Why is only one end at rest when a rope is attached to a cube? [duplicate]

I know there is something wrong in the way I think about physics generally, but I don't know what it is. Suppose there is a cube with a hook on one face and a rope attached to that hook (see diagram)....
