When I pull a rope attached to a block, does the rope OR the block pull me back? If so, with what force?

I am having a hard time understanding the tension force, especially when thinking about it at a molecular level. Suppose I have a rope attached to a block which is sitting on frictionless surface. ...

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 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 ...

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 ...

Newtons third law explanation on a push of table [duplicate]

I read this example of pushing a table with your hands. So the force is applied on the table to push and the table exerts the same amount of force on our hands. My question is, if the forces are ...

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?

Work done by the piston versus work done by the surrounding

Suppose a massless, frictionless piston assembly initially has a higher pressure than the external (atmospheric) pressure, and it is pinned so that the piston does not move. Once the pin is removed, ...

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 ...
