What are the formulae?

Answer 1

Work(W) = Force(F) x Distance (S)

Power(P) = Force(F) x Distance (S) divided by time

Kinetic Energy (Ek) = 1/2 Mass (M) x Velocity(V) Squared (^2)

Potential Energy (Ep) = Mass (M) x Gravity (G) x Height (H)

Force (F) = Mass (M) x Gravity (G)

Just woke up, all that's in my head at the moment but i will add more soon.

Answer 2

Weight (W)= d/t

distance (d)= W x t

time (t)= W/t

That is total rubbish. Someone seems to have weight confused with speed!

Formula weights are often used when things are being added together but some of these are more important than others so you give them more weight.

For example, your final score in a subject may depend on some coursework and an exam but the school decides that the exam is twice as important as the coursework. Then if C and E are the percentage marks that you get in the two parts, your overall percentage would be

(1*C + 2*E)/(1 + 2)

The weights associated with the two parts are 1 and 2 - although they could be any numbers in the same ratio. Just remember to divide by the sum of the weights. You can have any number of weights but their sum must be non-zero. The weights can be negative (in mechanics, for example).
