[LAB] Experiment 3: Conservation Of Energy Flashcards
the energy of motion of an object
Kinetic Energy
the energy of an object due to its vertical position relative to a reference point (such as the surface of the earth).
Gravitational Potential Energy
An object at a given height has a potential energy relative to a ____ reference point.
lower
If the object is dropped, it gains ____________ and its ____________ is decreased as it falls.
Kinetic Energy
Potential Energy
When an object is lifted, its ___________ changes depending on its mass, the acceleration due to gravity and its _____________
Gravitational Potential Energy
Height
it states that energy is neither created nor destroyed; it can only be transferred or transformed to other forms of energy.
Law of conservation of energy
Final Velocity formula
V = V0 - gt
“v” means

“g” means
the acceleration of gravity
“t”
time of fall
“V0”
the initial velocity of the ball
