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 ...
