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
3 lut 2023 · A contact force is defined as the force between two objects that are in physical contact. For example, kicking a soccer ball is a contact force since physical contact is between the foot and the ball. A non-contact force is defined as the force between two objects that are not in physical contact.
• Intermolecular Force (IMF): between molecules. This is the force that holds molecules together. It is a form of “stickiness” between molecules. Examples of intermolecular forces are London dispersion forces (LDF), dipole-dipole forces (DDF), and hydrogen bridging forces (HBF). When we use the word “force” we are referring to ...

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.
A force is a push or a pull upon an object resulting from the object's interaction with another object. There are two categories of forces: contact forces and forces acting at a distance. Contact forces occur when two objects are in physical contact whereas forces acting at a distance occur between object typically not in contact.
Newton's 2nd law in the form Fy = M ay. W1 is the force of gravity on mass M1 and W2 is the force of gravity on mass M2. W1 = M1 g and W2 =M2 g. T1 is the tension force on M1 due to the attached rope and T2 is the tension force on M2 due to the attached rope.
