Physcis Equations

Work Done(J) =

distance (M) x force(N)

(J= M x N)

Force(N)=

Mass(Kg) x Accleration(m/s) SQUARED

(N= Kg x m/s(squared))

Speed (m/s)=

distance(M)/time(s)

(m/s= M x s)

Power (W)=

Work Done (J) / Time (s)

(W= J / s)

Weight(N)=

Mass(Kg) x Graviatational potential strength(N/Kg)

(N=Kg x N/Kg)

Kinectic Energy (KE)-

0.5 x Mass (Kg) x Velocity(v) (SQUARED)

(0.5 x Kg x V(SQUARED))

Acceleration (m/s(SQUARED))=

Change in velocity(m/s) / time(s)

(m/s(SQUARED)= m/s / s)

Momentum(Kgm/s)=

Mass (Kg) x Velocity (m/s)

(Kgm/s= Kg x m/s)

Current (A)=

Charge (C) / time (s)
(A= C/ s)

Resistance(r)=

Potential difference(V) / Current (A)
(r=V / A)

Stopping distance=

thinking distance + braking distance
