Formula; F = m x a F = force M= mass of object A= acceleration

+ info

TThe unit for force is newtons(N)

In Physics, force is defined as: The push or pull on an object with mass causes it to change its velocity. Force is an external agent capable of changing a body's state of rest or motion. It has a magnitude and a direction.

Contact force is a force that is applied by objects in contact with each other. The contact force acts on a point of direct contact between the two objects. This force can either be continuous as a continuous force or can be momentary in the form of an impulse.

A non-contact force is a force which acts on an object without coming physically in contact with it. The most familiar non-contact force is gravity, which confers weight.

They're two types of forces which are catergorized into to sections,non- contact force and contact force

Contact Forces

Air resistance

Tension

Friction

Friction is a force that resists the sliding or rolling of one solid object over another. Frictional forces, such as the traction needed to walk without slipping, may be beneficial, but they also present a great measure of opposition to motion.

Air resistance is a kind of friction that occurs between air and another object. It is the opposing force that the object experiences as it passes through the air. Air resistance and gravity are the two fixed forces of nature which move on any object lifted from the earth and moved through the air

Tension is defined as the force transmitted through a rope, string or wire when pulled by forces acting from opposite sides. The tension force is directed over the length of the wire and pulls energy equally on the bodies at the end.

The attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron.

The force of attraction between any two bodies is directly proportional to the product of their masses and is inversely proportional to the square of the distance between them.

The study of electromagnetic phenomena that occur when there are no moving charges—i.e., after a static equilibrium has been established. Charges reach their equilibrium positions rapidly, because the electric force is extremely strong.

A vector is a quantity or phenomenon that has two independent properties: magnitude and direction. The term also denotes the mathematical or geometrical representation of such a quantity. Examples of vectors in nature are velocity, momentum, force, electromagnetic fields and weight.

a Scalar is a physical quantity that is completely described by its magnitude. Examples of scalars are volume, density, speed, energy, mass, and time. Other quantities, such as force and velocity, have both magnitude and direction and are called vectors.

Fun Facts

1.Particles can behave differently when observed 2.Time goes faster at the top of the building 3. Water can boil and freeze at the same temperature 4.The sun doesn’t change color during sunset 5.Water slows down light.
