An example of a force which acts at a distance is
a) tension
b) weight
c) friction
d) normal force
Isn't the answer c) the further an object goes the more resistance?
The correct answer is b) weight.
To arrive at the correct answer, we need to understand the concept of forces acting at a distance. A force that acts at a distance, also known as a non-contact force, is a force that affects an object without direct physical contact.
In the given options, tension, friction, and normal force are contact forces, meaning they require physical contact between objects to exert their influence. These forces occur when objects are in direct contact with each other.
Weight, on the other hand, is an example of a force that acts at a distance. It is the force exerted by gravity on an object. Gravity is an attractive force that pulls objects towards each other, and it doesn't require direct physical contact to act. For example, the gravitational force of the Earth acts on objects, causing them to be pulled towards the ground.
As for your statement about resistance increasing as an object goes further, it seems like you may be referring to friction. Friction is a contact force that opposes the motion of an object when it slides against or through a medium, such as when a box slides on the ground. The frictional force between the object and the surface it is moving on can indeed increase with distance traveled, particularly if factors like surface roughness or applied force remain the same.
In summary, weight is the correct answer because it is an example of a force that acts at a distance, while friction is a contact force that can increase resistance as an object moves further.
