Meaning, Effects and Equations of Force
Force changes motion or shape. Its general law is F⃗ = dp⃗/dt; with constant mass and p⃗ = mv⃗, it becomes F⃗ = ma⃗.
Open article →Contact and Non-Contact Forces
Contact forces act through touching, whereas gravity and magnetism act across separation without physical contact.
Open article →Resultant Force and Translational Equilibrium
The resultant is the vector sum of all forces. It produces acceleration; when the vector sum is zero, momentum stays constant and translational equilibrium holds.
Open article →Friction: Types, Factors and Control
Friction opposes relative motion; static, sliding and rolling forms depend on surfaces, load and contact area and can be controlled by lubrication or bearings.
