A rotating fan blade has kinetic energy when rotating with constant angular velocity when the angular velocity is reduced to one third what will happen to the kinetic energy?
It will decrease by a factor 9.
What energy is spinning tops?
a spinning top has bothRotational kinetic energy and angular momentum in play as it spins...
Why is green energy important to the future of plants?
By increasing our dependence on green energy our dependence on fossil fuel will decrease and hence a balance of different gases in the air will be maintained. Thus plants will be saved from effects of climate change.
Can neither be created or destroyed?
-- linear momentum -- angular momentum -- the sum of mass and energy
What is another name for the Law of Conservation of Energy?
angular momemtum
Why is the dependence on fossil fuels unsustainable?
Because they soon will run out and they are not renewable source of energy.
A benefit of green purchasing is the reduction of dependence on foreign sources of energy True or False?
True
Why did carter create department of energy?

Why did Carter create the Department of Energy?
He thought the us was too dependent on foriegn oil
Why is Japan becoming nuclear?
Japan reduces its dependence on imported oil when inreasing the contribution of nuclear energy in covering consumer energy requirements.
What is the difference between angular velocity and angular momentum?
angular momentum and angular velocity
Why does us need to find alternative energy sources?
Dependence on fossil fuels causes environmental damage.
