What energy transformations occur in a bike going up and down a hill?
When a bike goes up a hill, mechanical energy from pedaling is converted to gravitational potential energy as the bike gains height. When the bike goes down the hill, the gravitational potential energy is converted to kinetic energy as the bike accelerates. Frictional forces also convert some of the energy to heat.
If a ball was rolling down a hill what forces would be involved I really need help Thnx?
The main forces involved in the ball rolling down the hill would be gravity, which is pulling the ball downhill, and friction, which is resisting the ball's motion and slowing it down. Additionally, if there's wind or air resistance, that force would also be acting on the ball.
What is the name for going down a hill on your bike with out peddling?
Coasting.
What two forces slows down skiers when going down a hill?
The two forces that slow down skiers when going down a hill are friction and air resistance. Friction occurs between the skis and the snow, as well as between the skis and the boots, causing a resistance that reduces the speed. Air resistance is the force exerted by the air on the skier as they move downhill, acting in the opposite direction to the skier's motion and further slowing them down.
Does momentum make a bike move down a hill?
Momentum is the product of mass and velocity which infers motion taking place. If the bike was moving then yes it would make it go downhill. The real culprit would be gravity if the bike was not already in motion. The hill is an incline and the bike is being pulled by gravity down that incline.

Who was the 2007 down hill mountain bike champion?
Sam Hill

Why are bike brakes hot after slowing a bike at the bottom of a steep hill?
That is because of Friction. It is called heat friction and when you slow down after the brakes rub so hard against each other, it generates a lot of heat. also, you can check Wikipedia for more about heat friction.
How do you get faster on a bike when you have stopped peddling?
Cycle down a hill.

How does brakes and steering of a bicycle help with speed?
When going down a hill, you will pick up much more speed than if on flat roads. If you don't have brakes, you have very little chance of slowing down if something/someone goes infront of your path. The handlebars of a bike don't really affect the speed of the bike, that is more to do with navigation.
Why do river flow so slowly?
at the bottom of a hill the ground becomes flatter slowing the river down.
Suppose Sharon rides her bike at a speed of 10 ms as she rides up a hill her speed decreases to 5 ms is her acceleration positive or negative?
I would say positive, as she starts the incline of the hill, she has to pedel harder and harder, whilst doing this she would be slowing down, so yeah, positive
A rollercoaster heading down the hill?
When a roller coaster picks up speed going down a hill over time, this is known as acceleration. Acceleration can also include slowing down or changing direction in turns or loops.
