IGCSE Physics notes & exam tips and techniques

Velocity :
Displacement/Time

Acceleration =
Change in Velocity (m/s)/Time(s)

Newton's 2nd Law : Force (N) = Mass (kg) x Acceleration (m/s2)


Weight (N) = Mass (kg) x Gravitational pull (m/s)

Moments (Nm) =
Force (N) x Perpendicular distance (m)


Hooke's law = Force applied (N) =
Spring constant (N/m) x Extension



Momentum(kgm/s) Mass (kg) =
.
x Velocity (m/st


Impulse (Ns) =
Change in momentum



Kinetic energy= 2 x Mass (kg) x velocity (m/s2)


Work Done (5) = Force applied (N) x Distance moved in direction (m)




Power (W) = Work done (5) / time (s]
