No the can go faster downhill or uphill
It depends... the object could be falling, going straight, going uphill or going downhill.
Gravity. The car is heavy and doesnt want to move, so you must excelerate to make the car go uphill. If a car is going downhill, the is no need to excelerate because gravity is pulling the car downhill.
If you're rolling downhill - gravity. If you're going along on the flat - the pedalling effort of the rider.
because if you going down hill its faster because its a mountain
I would suppose it would matter if you were going uphill or downhill.
Gravity adds a force (kgs) going downhill = sin (incline angle) * mass vehicle (kgs) and detracts the force when going uphill (same equation)
11mpg loaded. 11.25mpg unloaded. 11.5mpg going downhill. 10.75mpg going uphill. 10.5mpg going uphill loaded. Subtract 1mpg if it's raining. Add 1mpg if you drive less than 65.
Average speed = Distance travelled/Time taken. And that applies whether the object is going downhill, uphill or is on a roller coaster.
Only while going uphill or while on pavement other than that, you should keep it pretty loss especially while going downhill
For cardiovascular health, it is more beneficial to do sprint walk or jogging. Running uphill seems better but researches are going on to describe which one is more beneficial. Consult your doctor if you are suffering from a heart disorder.
Depends on the gearing. On a bike with several gears, there'll usually be a few that make pedalling real easy, which'd make going uphill easy too. Slow, but easy.
