Question
PRE LAB 71.
Suppose you have two equal mass objects both on a gentle
incline. One is a glider on an air track while the other is a ball
on a straight slope. The air track and the slope have the same
slope angle. You release them at the same time and at the same
distance from the bottom of the slope. You note that neither loses
any significant amount of energy to friction as the air track has
very low friction and the ball rolls down without slipping or
sliding. (0.5 points total)
a)Explain what type of energy both objects have just before
they are released. Do both objects initially have the same amount
of energy? Before they are released, they both have gravitational
potential energy, which is equal to the product of their weight;
height and acceleration due to gravity. Since, both objects are of
equal masses and released at the same distance from the bottom of
slope. Both objects have same energy of energy initially.
