Conservation of energy In the examples you have examined in this lab, as the coaster travels down the track its gravitational potential energy decreases, and its kinetic energy increases. At any point along the path of the coaster, the potential energy plus the kinetic energy add up to the same value. In the absence of friction and air resistance, we find that the total energy (kinetic plus potential) stays the same. For this reason, physicists call the total energy a...

Given the formula of the kinetic energy of a particle m
with
speed v:
KE = 1⁄2mv2 ,
and the formula of the gravitational potential energy:
PE = -GMEm/R,
where G is gravitational constant and ME and R=6378 km are the
mass and the radius of Earth. Now the particle is shot from Earth
surface to space. Find the minimum required initial speed for this
particle to completely escape the influence of Earth gravity (i.e.
PE=0). Notice that the gravitational...
