All Equations
FORCES
Speed
Speed (m/s) = Distance (m) x Time (s)


Acceleration
Acceleration (m/s2) = Change in Velocity (m/s) ÷ Time taken for change (s)
C(V)=A x T


Stopping Distance
Thinking distance + Braking distance = Stopping distance


Force & Acceleration
Force (N) = Mass (kg) x Acceleration (m/s2)…

Kinetic Energy
Kinetic Energy (J) = ½ x Mass (kg) x Speed (m/s)

Momentum
(P)Momentum (kg m/s) = Mass (kg) x Velocity (m/s)
Pimp=My x Van

Change In Momentum
Change in momentum (kg m/s)= Force (N) x Time(s)
C=F x T


Force & Elasticity
Force(N)= Spring Constant(K) (N/m) x Extension(M)…

ELECTRICITY
Potential Difference
Potential difference (V) = Current (A or I) x Resistance ( or R)


Power & Energy
Power (W) = Energy (J) ÷ Time (s)


Power & Current
Power (W) = Potential difference (V) x Current (A or I)


Charge
Charge (C) = Current (A) x Time (s)
