### Can force be applied without accelerating?

When I push against a wall, I am applying force on the wall and the wall applies an equal force against mine therefore the wall doesn't move and neither does my hand. But isn't acceleration required ...

### Doubt on Newton's third law of motion [duplicate]

Okay, so if I have 2 blocks of different masses 4kg and 2kg placed side by side with possibly a distance of 1 molecule between them (sorry if the diagram doesn't show that). There is negligible ...

### 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 ...

### How are objects able to move even after newton's third law of motion [duplicate]

I can't understand at all why objects move even though after newton's third law.I also have a doubt in following example If we apply a force on an object the object applies a backward push on us ...

### 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 ...

### Clarify Torque and static friction [duplicate]

I came to this problem and solved it but I don't fully understand how this works. The problem is: A 200lb man climbs to the top of a 20ft ladder that is leaning against a smooth wall at an angle ...

### 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 ...

### How can any object move? [duplicate]

If an object A exerts a force on another object B, an equal and opposite force will be applied on object A by object B, so that means for a force to be applied on object B by object A, a force must ...

### If every object could give an equal and opposite force to what we apply then why do the objects exhibit translatory and rotational motion? [duplicate]

If I push a block on a frictionless surface with enough force, it begins to move. Shouldn't it be standing still if it exerts an equal force on me as per 3rd law?

### Force (Newton's third law of motion) [duplicate]

When we apply a force, there's always a reaction force too. Why do forces always come in pairs?

### Normal reaction by sand [duplicate]

Newton's laws states that for every action there is an equal and opposite reaction. That is why we do not sink in ground because we apply a force of mg on the ground and the ground responds with a ...

### What are the forces acting on a book kept on the ground? [closed]

If we exclude the motion due to the rotation of the Earth, what are the forces acting on the book? I know about the force of mg acting on the book and its opposite acting on the Earth, but I have some ...

### If Newton's third law is true, why can we sink in sand? [duplicate]

Newton's third law of motion states that every action has an equal and opposite reaction. That is the reason we do not sink into the earth, because when our weight exerts a force on the earth it also ...
