Part 1: 1. Select a suitable initial length and mass for the pendulum (for which the
pendulum does not swing too fast or too slow) for example 30 cm and 1.0 kg.
2. Start by displacing the pendulum through a small angle (less than 10°) then
release it.
3. Complete the table below.

no simpler subs form complex ones. synthesise = make

it breaks and dirupture other materials and other sencews from the bottom

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
