The grip of a tire is due to the force of friction, and the force of friction is directly proportional to the weight of the vehicle on the tire. On a level road, the weight of any body is vertically down, and this results in a high value of weight pushing down on the tire, which gives us high value of friction and strong grip.
By comparison, when going uphill or downhill, the weight of any vehicle is resolved into two components. One of the components will be a "down" component, but it will not be as great as the actual weight of the vehicle on level ground. This will result in a lower force of friction which results in a more loose grip of the tires.
No the can go faster downhill or uphill
noo
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.
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.
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
Simple blood pressure rise triggers nausea and a stressed feeling in general with an increase heart rate when going up hill ,especially when over weight
