✅ 1. Work W=F⋅d⋅cosθ Where:W = Work done (Joule)F = Force applied (N)d = Displacement (m)θ = Angle between force and displacement W=F⋅d⋅cosθ W=∫F⋅dx W=0 (Because force and displacement are perpendicular) W=m⋅g⋅h Where:m = Mass (kg)g = Acceleration due to gravity (9.8 m/s²)h = Height (m) W=−f⋅d Where:f = Frictional forced = Displacement W=m⋅g⋅h ✅ 2. Energy […]

✅ 1. Newton’s Laws of Motion A body continues in its state of rest or uniform motion unless acted upon by an external force.A body continues in its state of rest or uniform motion unless acted upon by an external force. F=m⋅a Where:F= Force (N)m= Mass (kg)a=Acceleration (m/s²) For every action, there is an equal and opposite reaction.For every action, there is an equal and opposite reaction. ✅ 2. Force and Acceleration Fnet=m⋅a W=m⋅g Where:W= Weight (N)g= Acceleration due to gravity (9.8 m/s2)(9.8m/s2) F=ΔpΔt Where:Δp= Change in momentumΔt= Time interval F=m⋅g⋅sinθ N=m.g⋅cosθ (Normal force)Where:θ = Angle of inclination ✅ 3. Friction f=μ⋅N Where:μ = Coefficient of frictionN = Normal force fs≤μs⋅N fk=μk⋅N fr=μr⋅N
