Great question !

The rate at which an object covers distance, without worrying
about the direction it's moving, is the object's SPEED .

When the direction is also given, then you have the object's VELOCITY.


This question is important.  It gives us a chance to point out that
"velocity" is not just a fancy word for speed that you use when you
want to sound smart.  There's actually an important difference between
'speed' and 'velocity'.

Which has a larger resistance, a 60 W lightbulb or a 100 W lightbulb? Which has a larger resistance, a 60 W lightbulb or a 100 W
Luba_88 [7]

You really can't tell.

Power = I^2 × R = V^2 / R ( unit in Watt)

For P = I^2 × R

Where we have P directly proportional to R, increase in Power leads to increase in R

So if we have 100 will have higher resistance

For P = V^2/R

Power is inversely proportional to resistance.

So increase in Power leads to decrease in resistance.

60 watt will have a higher resistance.
