Question

Identify the energy as potential or kinetic

a) ice skating

b) a milkshake

c) gas in the tank

Answer #1

Ans. **#A. Ice skating:** The energy associated
with a particle due to its **motion** is said to its
**kinetic energy**.
Ice skating indicates a person in motion. So, the energy associated
with a person enjoying ice skating is its kinetic energy.

**#B. Milkshake:** A milkshake consists of numerous
molecules like glucose, proteins, fats, etc.. The atoms bonded
through chemical bonds in a molecule have chemical potential energy
stored in the bond. Therefore, the energy associated with milkshake
is **chemical potential energy**.

**#C.** **Gas in a tank:** The gas
molecules confined in aby vessel (or when free) are under constant
motion. So, the energy associated with gas molecules in the vessel
is its **kinetic
energy**.

You are ice skating at 13 m/s toward a grizzly bear who is in
turn skating 4 m/s toward you. Your weight is 756 N and the bear is
900 N. Immediately after the collision you are moving at 8 m/s in
your original direction. Neglect external horizontal forces applied
by the ice to the skaters during the collision. What is the
velocity of the bear immediately after the collision? Calculate the
decrease in total kinetic energy of both you...

I need a summary on mechanical energy, including potential and
kinetic energy. Please use the example of a skater in a ramp (at
the top of the ramp the skater has all potential energy no kinetic
energy, and at the bottom of the ramp the skater has no potential
energy all kinetic energy). Please explain why a situation's
potential+kinetic energy is equal to the total amount of mechanical
energy.
