gravity is the one to blame . gravity pulls down the biker closer to earth so it goes faster going down and slower going down
The shape of of the villi really matters. Because if its down then it goes faster if its like a hill it goes slow but then gets faster.
Yes because it is just like a ball rolling down a hill; it obviously goes faster.
it affects it by if like say for instance it goes up a hill the speed would slow down or if u went down a hill then it would go faster.
The potential energy of the skier is converted into kinetic energy as they go down the hill due to gravity. This kinetic energy allows the skier to move faster and pick up speed.
push it down a hill
Gravity pulls it down and the weight of a car is less dense than a hill and therefore it goes down
The skier going up the hill gains potential energy due to its height increase, which is stored energy that can be released when the skier goes back down the hill. As the skier goes down the hill, the potential energy is converted into kinetic energy, which is the energy of motion.
Cycle down a hill.
drive down hill
Yes, the surface of a hill can affect how fast a ball will roll down it. A smoother surface will have less friction, allowing the ball to roll faster, while a rougher surface will create more friction and slow the ball down. Additionally, the incline of the hill will also impact the speed of the ball as steeper hills will cause the ball to accelerate more quickly.
