Energy: the capacity for vigorous activity; available power.
Kinetic Energy: the energy of a body or a system with respect to the motion of the body or of the particles in the system.
Law of Conservation of Energy: energy cannot be created or destroyed, but it can be transferred or transformed from one form to another.
Potential Energy: the energy of a body or a system with respect to the position of the body or the arrangement of the particles of the system.
Transfer: to move energy from one to another.
Transform: to change in form, appearance, or structure; metamorphose.

next time you need definitions quickly looking up a dictionary would be faster, anyways hopefully this can be helpful.

In the real world, the pendulum in a clock eventually comes to a stop. Someone or something needs to supply energy for the clock

Leno4ka [110]

Answer:

USING LAW OF CONSERVATION OF ENERGY

Explanation:

As we know that energy can not be created nor be destroyed.The pendulum cannot continue moving on its own because it meets energy losses due to friction.Its energy is converted into heat energy which dissipates in the air

Answer:

Explanation:

1. $V_{x}$ = $V_{0}$ * cos $\alpha$ ⇒ 16*cos32 ≈ 13.6 m/s (13.56)

2. $V_{y}$ = $V_{0}$ * sin $\alpha$ ⇒ 16* sin32 ≈ 9.4 m/s

3. $y_{max}$ = $\frac{v_{0}^2*sin^2\alpha}{2g}$ = $\frac{16^2*sin^232}{2*9.8}$ (the g (gravity) depends on the country but i'll take the average g which is 9.2m/s^2)
