What is gravitational potential energy?
Energy stored when an object gains height
Ep grav
What is the symbol for gravitation potential energy?
Gravitational potential energy → Kinetic energy
What energy change occurs when an object loses height (falls)?
What three things is gravitational potential energy dependent on?
Mass, strength of gravity and the change in height
How is gravitational potential energy calculated?
By multiplying mass, the strength of gravity and the change in height
What is the equation for gravitational potential energy?
ΔEp grav = m × g × Δh
Δ is the Greek letter 'delta' which means 'change in'
In the equation 'ΔEp grav = m × g × Δh', what does 'Δ' represent?
gravitational potential energy
an icicle hanging from a rooftop
Change in gravitational potential energy
In the equation 'ΔEp grav = m × g × Δh', what does 'ΔEp grav' represent?
mass
a body of coherent matter, usually of indefinite shape and often of considerable size
the strength of gravity
In the equation 'ΔEp grav = m × g × Δh', what does 'g' represent?
height
displacement in the y-axis; dy
change in height
In the equation 'ΔEp grav = m × g × Δh', what does 'Δh' represent?
ΔEp grav = Fw/F grav × Δh
Since mass × gravity is equal to weight force, what is another way the equation can be written?
Joules (J)
Heat units
Fw = ΔEp grav ÷ Δh
What is the equation to calculate the weight force from the gravitational potential energy and the change in height?
Δh = ΔEp grav ÷ Fw
What is the equation to calculate the change in height from the gravitational potential energy and the weight force?
