Question

according to the third law of motion when we push an object the object pushes us back with equal and opposite force if the object is a massive truck parked along the roadside it will probably not move even if we apply force on it justified by this answering that two equal and opposite force cancel each other comment on this logic and explain why the truck does not move

Answer 1

Action and reaction can never cancel each other because they always acts on two different bodies.
The force of friction between truck's tyres and the road is very large. Also. the weight of the truck is massive. so when we push truck it does not move.

Hope it helps u.

Answer 2

The truck doesn't move because action and reaction doesn't cancel each other and the mass of the truck is also huge.So, when the child pushes the truck he could not be able to change the position of the truck
