Potential in Kinetic energy Flashcards
What is kinetic energy?
Kinetic energy is when an object is moving.
What is potential energy?
Potential energy is when an object not moving.
Can momentum be hidden to human eyes like how kinetic energy can be hidden as heat?
No it can’t.
What is energy, and how is it classified?
it is stored.
How is potential energy classified?
Gravitational, elastic, magnetic, and electric.
Explain elastic potential energy with examples.
The energy that an object has in it due to being deformation of its shape.
Explain gravitational potential energy with examples.
When an object falls to the ground, all of the PEG at the maximum height is converted to KE at the bottom.
Can momentum be hidden to human eyes like how kinetic energy can be hidden as heat?
In a regular mechanical system with macroscopic parts, momentum cannot be “hidden” to human eyes.
Why is light pure energy?
Energy is merely one of the factors that it carries, including frequency, wavelength and even spin.
Does an electron in an atom move at all?
They either move continuously around the nucleus in certain stationary orbits or discontinuously jump between these orbits.
