What is the formula for gravitational potential energy?
Think about the variables involved: mass, gravity, and height.
What type of energy is stored in a compressed rubber band?
Consider what happens to the band when it is released.
Which type of energy is associated with an object's height?
Think about how height affects energy.
True or False: Elastic potential energy is stored when an object is compressed or stretched.
Consider examples of springs or rubber bands.
A 2 kg object is dropped from a height of 20 meters. Calculate its gravitational potential energy at that height.
Use the gravitational potential energy formula with mass, gravity, and height.
A spring with a spring constant of 150 N/m is stretched to 0.3 m. What is the elastic potential energy stored in it?
Be sure to square the displacement when calculating the energy.
