How does the energy associated with a bicycle change as it speeds up going downhill?
The energy associated with a bicycle changes as it speeds up going downhill due to the fact that potential energy is converted to kinetic energy. The potential energy is the energy of the position. The kinetic energy is the energy of movement.
Why are road accidents at higher speeds more disastrous as compared to those at low speeds?
Higher speeds involve higher forces which do more damge in breaking bones, etc. Ther force is f=ma = mdv/dt, the higher the speed the greater the deceleration on impact thus causing greater force on structures. There is also higher energy in higher speeds. At low speeds the energy and forces are smaller. The energy goes up by the speed squared, so twice the speed gives four times the energy. Twice the speed gives twice the force. The damage relates to the force the structures can take before damage.
How do you find the average velocity if there are two different speeds?
We sum the two different speeds and devided by two
Can two people be moving at different speeds but have the same kenetic energy?
yes. KE=1/2mv2, mass is also a factor that can change KE
The different molecules that make up the air in a room have on average the same kinetic energy how does the speed of the different air molecules depend on their masses?
If mixed together, molecules with various masses will move at different speeds related to their mass.
What does energy flow mean?
Energy flow is the movement of energy from one place to another. This movement occurs at different speeds through different mediums.
Can two people be moving at the different speeds and have the same kinetic energy?
Sure. Kinetic energy depends on both mass and speed. So two objects could have different speeds, but if their masses are also different by just the right amount, their KE's could be equal.
Is energy consumption different when fan runs at two different speeds?
Yes. If a fan is moving faster, more work is having to be done to it and therefore more energy is being used.
Does enzyme contains high sugar?
No. An enzyme is a chemical that speeds up chemical reactions without adding any energy to them. Sugar is an energy source that makes some chemical reactions happen. They are different things and work on different principles.
What energy speeds up a reaction?
This is the activation energy.
How do astronomers know the sun's surface rotates at different speeds?
Sunspots rotate at different speeds.

What is the need for motor speed control?
There are many application of motor speed control. Mixer in a food process application needs to run at different speeds. Machine needs to run at different speeds according to required production speed. There are plenty of such application for energy saving etc.
A moving car has kinetic energy If it speeds up until it is going four times faster than before...how much kinetic energy does it have in comparison?
Kinetic energy is proportional to velocity2, so if velocity is multiplied by four the kinetic energy is multiplied by sixteen

yes. KE=1/2mv2, mass is also a factor that can change KE
