PLEASE HELP (NO LINKS!)As the pendulum swings from position A to position B, what is the relationship of kinetic energy to potential energy (neglect friction)? (5
points)
The kinetic energy increase is equal to the potential energy decrease.
The potential energy increase is equal to the kinetic energy decrease.
The kinetic energy and potential energy remain the same.
The kinetic energy increase is more than the potential energy decrease.

the kinetic energy decrease is equal to potential energy increase

the kinetic energy increase is equal to the potential energy decrease

Explanation:

as the pendulum swings down, it goes faster and gains kinetic energy, but loses potential energy.

e/c, where e is its total energy

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.
