What is mechanical energy?
Energy transformation that takes place when rubbing your hands together.
What is mechanical to thermal?
As the mass of an object moving at a given speed decreases, its kinetic energy will ______________________.
What is decreases?
Energy formed when an atom splits apart or when two atoms join to form one.
What is nuclear energy?
The type of energy that depends on mass and height.
What is potential energy?
As the speed of a falling object increases, its potential energy will _____________________.
What is decrease?
This is an example of electrical energy being changed to radiant energy.
What is lamp?
Type of energy that depends on speed of the object.
What is kinetic energy?
Wind turbines convert ____ energy into electrical energy.
What is mechanical?
When you drop a book on the floor, what happens to its original potential energy?
What is the potential energy was transformed to kinetic
his is a type of energy that travels in waves and can travel through empty space.
What is light energy
Type of energy that depends on the flow of electrons.
What is electrical energy?
What energy transformation happens when you crumble a paper?
A basketball is dropped from a height of 2m and another identical basketball is dropped from a height of 4m. Which ball has more kinetic energy just before it hits the ground?
hat is The basketball dropped from a height of 4m because it has more speed.
As a roller coaster car goes down a hill, its potential energy ________________ and its kinetic energy _______________.
What is decrease and increase
Type of energy stored in bonds of molecules.
What is chemical energy?
When you drop a tennis ball, it hits the floor and bounces back up. But, it does not reach the same height as before and each time bounce is smaller than the previous one. However, you notice the tennis ball is slightly warmer after it finishes bouncing. Explain how the law of conservation of energy is obeyed.
What is During each bounce, some of the kinetic energy of the ball in transferred into thermal energy. As a result, energy is not created or destroyed, but only changes form so that the law of conservation of energy is obeyed.
What energy transformation is happening in a clothe dryer?
Electrical to mechanical to thermal.
