According to Newton, which of these will determine if and how an object will move? 1. how much energy the object has
2. how unstable the object is
3. whether a net force acts on the object
4. he total mass of the object

Which best describes the difference between internal and thermal energy?

How much energy will be transferred to your eardrum while listening to this sound for 1.0 min?

Does the distance travelled by an oscillating mass between times t=0 and t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanation.
