Question 2
An object with a mass of $m$ is raised to a height of $h$ above a reference point. If the acceleration due to gravity is $g$, what is the gravitational potential energy of the object?
Question 3
A spring is compressed by a distance of $x$ from its equilibrium position. If the spring constant is $k$, which of the following expressions represents the elastic potential energy stored in the spring?
Question 4
A 0.5 kg ball is dropped from a height of $10 \text{ m}$. Assuming no air resistance and $g = 9.8 \text{ m/s}^2$, what is the gravitational potential energy of the ball just before it is dropped?
Question 5
A spring is stretched by $0.05 \text{ m}$ and stores $0.25 \text{ J}$ of elastic potential energy. What is the spring constant ($k$) of the spring?
