“Conservation of Energy with Toys”
Summary: In this activity students will use image processing tools to study the
motion of a spring-loaded toy. This will study the connections between elastic
potential energy, gravitational potential energy, and kinetic energy.
Elastic Potential Energy 𝑃𝐸 =
1
𝑘𝑥 2

Acceleration 𝑣𝑓 = 𝑣𝑖 + 𝑎𝑡

Gravitational Potential Energy 𝑃𝐸 = 𝑚𝑔ℎ Kinetic Energy 𝐾𝐸 = 𝑚𝑣 2

How can elastic potential energy be calculated?
How can gravitational potential energy be calculated?
Explain the Law of Conservation of Energy.
What do you predict will happen when additional mass is added to the toy?
What should be true about the kinetic energy of the toy just before hitting the
ground when it is compared to the original elastic potential energy, according to
the Law of Conservation of Energy?
