Q: In a tug of war, when one team is pulling with a force of 100 N and the other 80 N, what is the net force?
1 ans----- A push or pull on an object. A force can cause an object to accelerate, slow down, remain in place, or change shape. Gravity: A force attracting objects toward the center of the earth.
2 ans----- The SI unit of force is the newton, symbol N. The base units relevant to force are: The metre, unit of length — symbol m. The kilogram, unit of mass — symbol kg.
3 ans----- The net force is the vector sum of all the forces that act upon an object. That is to say, the net force is the sum of all the forces, taking into account the fact that a force is a vector and two forces of equal magnitude and opposite direction will cancel each other out.
4 ans----- 20
explanation of 4 and 20 is as follows------
A tug of war, where each team is pulling equally on the rope, is an example of balanced forces. The rope will have an acceleration of zero under the action of these balanced forces. It will therefore remain stationary. 'Changing motion' includes movement where the body is speeding up or slowing down.
hope it helps you!
