What is the formula for kinetic energy in SHM?
Remember the definition of kinetic energy.
Define potential energy in the context of SHM.
Consider the context of a spring system.
What type of energy is highest at the maximum displacement in SHM?
Think about the position of the mass.
True or False: The total mechanical energy in SHM increases over time.
Consider how energy is conserved throughout motion.
A mass-spring system oscillates with an amplitude of 0.3 m and a spring constant of 250 N/m. Calculate the total energy and its maximum kinetic energy if the mass is 1 kg.
Use the amplitude in the total energy formula.
A simple pendulum has a length of 1 m. If it swings with an amplitude of 0.1 m, what is the maximum potential energy at the peak if the mass is 0.5 kg?
Think about finding the effective height using a small angle.
