Question 1.
Define potential energy in your own words.
Show hintHide hint
Think about energy that is not currently in motion.
Question 2.
What is the formula for gravitational potential energy?
Show hintHide hint
What are the variables involved in calculating potential energy?
3Question 3.
What is the formula for gravitational potential energy?
- PE = mgh
- PE = 1/2 mv²
- PE = Fd
Show hintHide hint
Its variables depend on mass, height, and gravity.
4Question 4.
True or False: Potential energy can change into kinetic energy.
- True
- False
Show hintHide hint
Consider examples like falling objects.
Question 5.
A 12 kg rock is dropped from a height of 20 meters. Calculate the potential energy at the top and discuss what happens to this energy as it falls.
Show hintHide hint
Use PE = mgh for the calculation and consider energy transformation.
Question 6.
You have a pendulum with a mass of 3 kg that swings to a maximum height of 2 meters. Calculate the maximum potential energy and explain its role in the pendulum's motion.
Show hintHide hint
Think about the energy changes between the highest and lowest points of the swing.
