e force ? ◆━━━━━━◆❃◆━━━━━━◆✒ A force INVOLVES an interaction between two or more objects, and it CAUSES a push or pull between the objects are known as the force . Force is an external activity that can change position of any body.It has a magnitude and a direction.☞ There are many examples of forces in our everyday lives:✒ Weight force (i.e. the weight of something).✒ The force of a bat on the ball.✒ The force of the hair brush on hair when it is being brushed.━━━━━━━━━━━━━━━✒ The SI UNIT of force is Newton(N).✒ In SI base units ↠ kg·m/s²◆━━━━━━◆❃◆━━━━━━◆➽ Formula for Force :- ✒ The quantity of force is EXPRESSED by the vector product of mass (m) and acceleration (a). The equation or the formula for force can mathematically be expressed in the form of:Where,❥ m ↠ mass of the body ❥ a ↠acceleration❥ f ↠force ━━━━━━━━━━━━━━━☞ Extra shots :- ❥ Unit of force :- ✒ In the centimeter gram second system of unit (CGS unit) force is expressed in dyne.✒ In the standard international system of unit (SI unit) it is expressed in Newton (N).☞ Types of Force :- ➪ There are two types of forces based on their APPLICATIONS:✒Contact Force✒Non-Contact Force]✒ Forces that act on a body either directly or through a medium are called contact forces.➪ Examples of contact forces are:✒Muscular Force✒Mechanical Force✒Frictional Force]✒ Forces that act through spaces without making direct contact with the body are called non-contact forces.➪ Examples of non-contact forces are:✒Gravitational Force✒ Electrostatic Force✒ Magnetic Force━━━━━━━━━━━━━━━
