Answer:
- Waves with higher amplitude transfer HIGHER energy.
- Waves with higher frequency transfer HIGHER energy.
Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
When it has a magnetic field
No. Mechanical energy is not conserved. There's quite a bit of friction on the slide. So some of the potential energy is lost to heat on the way down, and the child arrives at the bottom with hot pants and less kinetic energy than you might expect.
