Forces are an interaction between TWO objects. It is not possible to have a force on an object and not have another object involved. Forces are vectors. They have magnitude and direction The unit ...

Friction is a force that always opposes motion. Force is measured in newtons (N). A force is a push or a pull. Contact forces arise between two objects which are in contact. Non-contact forces act ...

Newton’s Second Law of Motion states, “The force acting on an object is equal to the mass of that object times its acceleration.” ...

But on an orbital sense, the gravitational force between two objects depends on the mass of both the larger and the smaller object.

Measuring devices have become sensitive enough to detect the gravitational forces between tiny objects and may soon cross the quantum threshold.
