Question

1. What are the formulas for the two main types of energy?

Answer 1

Answers:

Kinetic Energy Formula: $KE = \frac{1}{2} mv^2$

Potential Energy Formula: $PE=mgh$

Explanations:

For KE:

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

For PE:

In the above equation, m represents the mass of the object, h represents the height of the object and g represents the gravitational field strength (9.8 N/kg on Earth) - sometimes referred to as the acceleration of gravity.
