# Newton's 3rd law applied to friction

I'm confused about how Newton's 3rd law applies to friction. If you slid an object across a table then the particles you are sliding against would exert the same force back, but wouldn`t this mean constant velocity since the object has equal acceleration in opposite directions, but it isnt really a force to begin with since if its sliding by itself then you are no longer exerting a force, the only force is the force of friction?

Please help, keep in mind Im new to physics and I only know the basics of newtonian laws.

• Can you make your question a bit more clear? – Normie Dec 16 '15 at 7:53
• Things accelerate because of the second and third law, since if one object exerts a force on another object that same force will be exerted on the object, a force means acceleration, which depends on the mass of the object. Im basically asking what will happen when an object accelerated by 5 newtons, exerts this force on another object. – Ben Dec 16 '15 at 8:16
• @Avik is right the question needs to be more clear. You are totally jumbling the concepts and your question needs to be revised. – Vinay5forPrime Dec 16 '15 at 11:47
