1. • • These forces take energy away from the system as the system progresses, energy that you can’t get back. These forces are path dependent; therefore it matters where the object starts and stops.

   What is a force in physics?

   • Explain. A force is a push or pull that acts upon an object as a result of that objects interactions with its surroundings. In this Lesson, The Physics Classroom differentiates between the various types of forces that an object could encounter. Some extra attention is given to the topic of friction and weight.

   What is a force of gravity?

   • The force of gravity is the force with which the earth, moon, or other massively large object attracts another object towards itself. By definition, this is the weight of the object. All objects upon earth experience a force of gravity that is directed "downward" towards the center of the earth.

   Which force is responsible for all interactions between particles and objects?

   • Forces are responsible for all the interactions between particles and objects. They can be divided into two categories: contact forces and non-contact forces. Gravity is one of the most important forces in the universe. An object with mass in a gravitational field experiences a force known as weight.

   Is force a vector quantity?

   • Force is a vector quantity that has both magnitude and direction. How to Find Force The force equation can be derived by using Newton’s Second Law, which states that the force (F) acting on an object is given by the product of its mass (m) and acceleration (a).

   What is friction force?

   • The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it. There are at least two types of friction force - sliding and static friction. Though it is not always the case, the friction force often opposes the motion of an object.

   What is an applied force?

   • An applied force is a force that is applied to an object by a person or another object. If a person is pushing a desk across the room, then there is an applied force acting upon the object. The applied force is the force exerted on the desk by the person.

   A moment is the turning effect of a force. Moments occur when forces cause objects to rotate about some pivot. The moment of a force is given by. Moment (N m) = Force (N) × perpendicular distance from the pivot (m) The SI unit for the moment is Newton metres (N m).

   An object requires a resultant force to be able to accelerate. Newton’s Second Law: The sum of the forces acting on an object is equal to the rate of change of momentum of the object. Newton’s Third Law: Every action has an equal and opposite reaction. If an object exerts a force on another object, then the other object must exert a force

   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. Force can be represented by vectors or expressed as a multiple of a standard force.
