What's the symbol for displacement in the Work Formula

• s

• d

• D

• S

If force acts on the opposite direction then the displacement is _____

• weaker than force

• negative

• positive

• greater than force

Power is defined as

• p = t/W, where t is time and W is work

• p = W/d, where W is work and d is the distance

• p = W/t, where W is work and t is time
