A stone has 390 J of energy and is moving with a speed of 12 m/s.

$$m=\frac{2KE}{v^2},\ \frac{2\left(390\right)}{12^2}$$ m = 5.42 kg

A 0.06 kg ball is moving with 75 J of energy.

$$v=\sqrt[]{\frac{2KE}{m}},\ v\sqrt[]{\frac{2\left(75\right)}{.06}}$$ v = 50 m/s

Types of Potential Energy

1. Elastic potential energy 2. Chemical potential energy 3. Gravitational potential energy

Elastic Potential Energy

Energy stored in objects being compressed or stretched. Examples include a bow and arrow, spring, and slingshot.

Chemical Potential Energy

Energy stored in chemical bonds of compounds. Examples include firewood, batteries, and food.

Gravitational Potential Energy (GPE)

GPE is the energy due to an object's position above the ground.

The formula for Gravitational Potential Energy is GPE = ham, where h is height, a is acceleration due to gravity, and m is mass.

A 5kg rock, dropped from 10 m would have how much GPE

$$GPE=ham,\ \left(10\right)\left(9.8\right)\left(5\right)$$ $$GPE=$$ 490 J

A Viking ship roller coaster has a mass of 36,000 kg and reaches a height of 20 m.

$$GPE=\left(36,000\right)\left(9.8\right)\left(20\right)$$ GPE = 7,056,000 J

A 1.5 kg apple pie has 13.44 J of gravitational potential energy.

$$h=\frac{GPE}{am}$$ h = 0.914 m
