When fireworks explode, chemical energy is transformed into thermal energy, mechanical energy, radiant energy, and sound energy.
What is the energy conversion of fireworks?
Some of the chemical energy stored in the fireworks is converted to kinetic energy to send the rocket skyward; some compresses the air rapidly, producing sound and still more energy is transformed into light of many colours.
What energy conversion takes place as a box slides to a stop on a horizontal table?
Elastic potential energy is converted into gravitational potential energy. What energy conversion takes place as a box slides to a stop on a horizontal table? a. Kinetic energy is converted into thermal energy.
What is the main energy transformation when a stretched slingshot releases a watermelon?
We know that when it’s released, the slingshot will give the watermelon kinetic energy. And because it raises the watermelon a height ℎ, it also gives that watermelon potential energy due to gravity.
When energy is transformed some energy is converted to?
Whenever energy is transformed, some energy is converted to thermal energy.
When a person is sledding down a hill where do they have the most kinetic energy?
At the bottom of the hill, you have the most kinetic energy because you are moving the fastest and all the potential energy has turned into kinetic. Sledding only works when there is snow on the ground, if you try to go sledding on a grassy hill it won’t be as fun because snow helps to eliminate friction.
What two things can make potential energy increase?
The amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds. Gravitational potential energy increases as weight and height increases.
At what point during the swing of a pendulum is the gravitational potential energy greatest or is it constant during the swing?
yes, because gravity is a conserved force (not path dependent). At what point during the swing of a pendulum is the gravitational potential energy greatest, or is it constant during the swing? At highest point where KE is lowest.
At what point does the ball have the most energy ignore air resistance?
At what point does the ball have the most energy? Ignore air resistance. At the highest point of its path.
