When a block is moved on a surface there is an equal and opposite force acting on it - Newton's Third law- therefore the net force is zero the how does the block moves?

-- The equal and opposite forces on it are the vertical forces ... the weight of the
block downward and the normal, constraint force of the surface upward. Since
the vertical forces are equal and opposite, the net vertical force on the object is
zero, and it has no vertical acceleration.
-- Nobody ever said that the block needs force to keep moving. In fact, it doesn't.
Once it's moving horizontally, no force is needed to keep it moving horizontally.
If it weren't for that pesky friction where it touches the surface, it would keep
moving forever with no force on it.

What is theExplanation of newtons third of motion?
Newtons thrid law of motion is that every action has an opposite and equal reaction acting upon it
The vector sum of 3 newtons and 4 newtons?
It depends on the angle between the two forces. It can be anything from 1 newton (if they're acting in exactly opposite directions) to 7 newtons (if they're acting in exactly the same direction).
Which of newtons law is related to transfer of momentum when a bat strike a ball?
for every force, there is equal force acting in the opposite direction
How many newtons does it take to lift an object?
It depends on how great the force is acting against the newtons.
An object has a mass of 180kg on the moon what is the force of gravity acting on the object of the moon?
The weight of a 180-kg mass on the surface of the moon, rounded, is 292.1 newtons (65.67 pounds) .
Measure of the force of gravity acting on an obect?
Weight in Newtons.
There is no motion when forces acting on an object are?
An object at rest will stay at rest unless acted upon by an external force - newtons 1st law of motion. It will stay at rest If no force is applied. Also if equal and opposite forces are applied (balanced) to a resting object it will remain at rest also - every action has an equal and opposite reaction - newtons 3rd law of motion
What forces are acting on the 10 kg weight?
98.07 newtons on earth.
When forces act in opposite direction?
When two equal forces act in opposite directions, they are called balanced forces, and no motion takes place. If they are unequal, than the weakest force is cancelled out, along with an equal amount of the strongest force. For example, if an object is being pushed on opposite sides with 7 and 10 newtons of force, then the 7 newton force will be entirely cancelled out, along with 7 newtons of the 10 newton force. This will leave a net force of 3 newtons acting on the object. If there is a net force (also called an unbalanced force), then motion will take place.
At what angle is the resultant force acting?
it is acting opposite the the equilibrium.
What is the resultant of two forces acting in opposite directions to each other?
Unequal combined forces trying to move in opposite directions would be the net force in one direction. Force is a vector quantity for any external effort that causes something to change a certain way.
What is the mass of an object if the force of gravity acting on its mass is 1033 Newtons?
If we have a force acting on a body and we know what that force is, and we also know that the force is gravity, we can solve because we know the force gravity exerts on a mass. If we take the total force acting on the body and divide it by the force of gravity per one unit of mass, we can find the number of units of mass that cause gravity to act on the object. We have 1033 Newtons of force acting on the object. Gravity pulls down with a force of 9.8 Newtons on 1 kilogram of mass. Our 1033 Newtons divided by 9.8 Newtons per kilogram = 105.41 kilograms
