Potential Energy and Kinetic Energy

Potential Energy

• Energy stored in an object because of its position, condition and shape

• Gravitational potential energy

• elastic potential energy

Gravitational Potential Energy

energy stored in the object because of its higher position from ground

E_g = mgh

Multiple Select

Quantity of gravitational potential energy depends on

• mass of object

• velocity of an object

• distance from surface of earth

• strength of earth's gravitational potential energy

Open Ended

What is the benefit of gravitational potential energy?

Elastic Potential Energy

• energy stored as a result of deformation of an elastic object as it is compressed or stretched

•  $E_e\ =\frac{1}{2}Fx$  

Kinetic Energy

Kinetic Energy

• energy possessed by an object due to its motion

•  $E_{k\ }=\ \frac{1}{2}mv^2$  

Multiple Select

amount of kinetic energy depends on

• mass of moving object

• speed

• distance from surface of earth

• strength of gravitational force
