Consider two objects A and B. The force which object A exerts on object B is equal and opposite to the force which object B exerts on object A: FAB = −FBA This law is popularly stated as the “law of action and reaction”, but in fact it deals with the forces between two objects.
The equation for universal gravitation thus takes the form: =, where F is the gravitational force acting between two objects, m 1 and m 2 are the masses of the objects, r is the distance between the centers of their masses, and G is the gravitational constant.
What is a force? A force is simply a push or a pull. A force is a vector, so it has a direction. The SI unit of force is the newton (N). 1 N = 1 kg m/s2. In addition, a force represents an interaction between objects. For instance, the Earth exerts a force on the pen and the pen exerts a force on the Earth. Each object involved in an
Chem101: General Chemistry Lecture 4 - Forces Between Particles I. Introduction A. Forces between Particles 1. The chemical and physical properties of matter result from interactions that take place between their constituent particles, i.e. their molecules and atoms. 2. For example a. Boiling points and melting points are determined by the ...
The Force Due to Friction : Friction is a force between two objects in relative motion. Friction is due to intermolecular forces between the atoms of the to solid objects. When we refer to friction, we mean the force of resistance between two solid object. "Air resistance" or "drag force" has some different properties and will
An intuitive definition of force —that is, a push or a pull—is a good place to start. We know that a push or a pull has both magnitude and direction (therefore, it is a vector quantity), so we can define force as the push or pull on an object with a specific magnitude and direction.
A force is a push or a pull. A force is a vector : it has a magnitude and a direction. Forces add like vectors, not like scalars. Example: Two forces, labeled F 1 and F 2, are both acting on the same object. The forces have the same magnitude F F F 12 oand are 90 apart in direction: F F F F F net total 1 2 ( F
