In a leap year does the earth move faster slower or at the same speed?

The earth moves at the same speed. A leap year is not caused by any physical change, but due to our system of measuring time and our reference calendars. A year - as defined by one rotation of the earth around the sun - is 365.25 days. Obviously this is inconvenient to note every year, the extra quarter of a day, 6 hours, before the new year starts. So instead, we round every year down to 365 days, and every 4 years add up the remainders, a total of 1 day, 24 hours. This keeps our calendars and time in sync with the physical definition of a year.

What does The length of day and night could be reprogrammed to compensate for the changing lengths of day and night throughout the year mean?
The Earth doesn't always rotate with the same speed. Ice melting or freezing near the poles, and other mass distributions, may change the speed of rotation. Also, the Earth rotates slower and slower, due to energy lost to friction (through the tides).As a result, now and then a "leap second" are added in the middle or at the end of the year, to make the official day match the astronomical day. That means that although usually a minute has 60 seconds, and a day has 86400 seconds, now and then you will have a minute with 61 seconds, and a day with 86401 seconds.The Earth doesn't always rotate with the same speed.

Will the earth always spin at this speed if not how will it change?
The Earth's rotational speed is gradually slowing. There are a number of instances where time calculations have meant that we periodically add a 'leap second' to bring the actual time back into sync with the Earth's rotation.
How many leap year on Jupiter?
There are only leap years on Earth, so there is no such thing as a leap year on Jupiter.
How fast can a frog leap?
The frog can leap as fast as a cheetah and the speed of that is, 57 miles per minute.
How does the earth move when its leap year?
The Earth moves the same in a leap year as it does in any other year. We have leap years because Earth takes about 365.25 days to go around the sun, not 365 days, so a leap year makes up for that in order to keep our calendars correct.
How many seconds in a Mercury leap year?
Leap years are only something that occur on Earth, so there is no such thing as a Mercury leap year.
