Class 11PhysicsNewton's Laws of Motion and FrictionThe Common Forces and Equilibrium of Concurrent Forces
MediumDefine force. What is contact force? Write two examples of field force.
(N/A) $1$. Definition of Force: Force is defined as a push or a pull acting on an object,which has the capacity to change the state of rest or uniform motion of the object or change its shape or size.
$2$. Contact Force: $A$ contact force is a force that acts on an object only when it comes in physical contact with another object. Examples include friction,tension,and normal force.
$3$. Field Force (Non-contact force): $A$ field force is a force that acts on an object even without any physical contact,typically through a field (like gravitational or electromagnetic field). Two examples are:
$(i)$ Gravitational force
(ii) Electrostatic force
