What sort of energy does she have at the bottom of the hill before she applies her brakes?

If she's coasted down the hill at some speed, then she'll be carrying kinetic energy at the bottom of the hill.

How law of conservation of energy applies to everyday basis?
It applies in the sense that you can NEVER get energy where there was none before, and you can NEVER destroy energy completely.
A 735 kg car moving at 20 ms brakes to a stop The brakes contain about 15 kg of iron which absorbs the energy What is the increase in temperature of the brakes?
To find the increase in temperature of the brakes, you need to calculate the total kinetic energy of the car before braking and then determine the amount of energy absorbed by the brakes during braking. Using the equation for kinetic energy (0.5 x mass x velocity^2) for the car before braking and equating it to the energy absorbed by the brakes, you can then find the increase in the temperature of the brakes using the specific heat capacity of iron.
What is the energie that can be changed but not lost or destroyed?
The energy that can be changed but not lost or destroyed is called kinetic energy. This type of energy is associated with the motion of an object and can be transformed into different forms of energy, such as potential energy or thermal energy, but it is always conserved.
Bicycle brakes energy conversion?
Brakes turn kinetic energy into heat.
What do brakes do?
A vehicals brakes convert kinetic energy into thermal energy through friction and dissipate the thermal energy into the atmosphere
What type of energy is found in brakes?
Heat energy
How The Law of Conservation of Energy Applies To Energy?
in closed systems
What are the different types of brakes?
The main types of brakes are disc brakes, drum brakes, and regenerative brakes. Disc brakes use calipers to squeeze pads against a rotor to create friction and slow down the vehicle. Drum brakes use shoes to press against the inside of a drum to generate friction. Regenerative brakes convert kinetic energy into electrical energy to slow down the vehicle.
When a bus brakes to a stop its kinetic energy transforms?
When a bus brakes to a stop, its kinetic energy transforms into heat energy due to friction between the brake pads and the wheels. This heat energy is dissipated into the surroundings.
What energy changes takes place when a moving car is stopped by brakes?
When a moving car is stopped by the brakes, the kinetic energy of the car is converted into thermal energy due to friction between the brake pads and the wheels. This thermal energy is then dissipated into the surrounding environment. Additionally, some of the kinetic energy may also be converted into sound energy if there is squealing from the brakes.
How do brakes stop a car?
Friction converts kinetic energy into heat energy.
Energy in the form of moition is?
The energy you put into something to make it move at a steady speed is called KINETIC ENERGY. It's the Kinetic Energy of a car that makes the brakes hot when you try to stop. The kinetic energy of the moving car becomes heat in the brakes of the stationary car which has lost its kinetic energy. There are two ways to get a car to the top of a hill. One is to start at the bottom and drive the car to the top and then stop again. This way, the engine pushed the car up the hill. The other way is to start a long way before the hill and build up speed along a flat road. Then you can turn off the engine and the car will coast to the top of the hill before it stops. This way, the engine put a lot of Kinetic Energy into the weight of the car before it got to the hill, and it was that Kinetic Energy which was used to get the car up the hill.
