Question

can energy be stored?
a 0.1 kg hat is hanging 1.8 meters above the ground.
how much gravitational potential energy does the hat have?
remember : $e_g = mgh$
$g = 10 \frac{m}{s^2}$
$e_g = ? j$

Explanation:

Step1: Identify given values

Mass \( m = 0.1 \, \text{kg} \), height \( h = 1.8 \, \text{m} \), gravity \( g = 10 \, \frac{\text{m}}{\text{s}^2} \)

Step2: Apply gravitational potential energy formula

Use \( E_g = mgh \). Substitute values: \( E_g = 0.1 \times 10 \times 1.8 \)

Step3: Calculate the result

\( 0.1 \times 10 = 1 \), then \( 1 \times 1.8 = 1.8 \)

Answer:

\( 1.8 \)
