    A force is a push or pull acting upon an object as a result of its interaction with another object. There are a variety of types of forces. Previously in this lesson, a variety of force types were placed into two broad category headings on the basis of whether the force resulted from the contact or non-contact of the two interacting objects.

    A force is a push or a pull that acts on an object due to the interaction with another object. Force is measured in newtons (N). Forces are divided into contact forces and non-contact...

    at the point of contact between two objects. Examples of contact forces include pushing or pulling objects with different parts of your body. Friction is a contact force between one object moving over another.

    Forces serve to change the velocity of an object, not to maintain its motion (contrary to the ideas of philosophers in ancient times). 4.1.2 Newton’s Second Law. Experiments show that objects have a property called mass which measures how their motion is influenced by forces. Mass is measured in kilograms in the SI system.

    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 interaction experiences a force. Question: Can an inanimate object like a pen or a desk exert a force?
