Energy that does not involve the large-scale motion or position of objects in a system is called:

A - Kinetic Energy

B - Potential Energy

C - Nonmechanical Energy

D - Conserved Energy

The flow of electrons through wires and components is known as: Particle Current Electric Current Positive Current Static Electricity

1. A tennis ball is dropped from a second story window. It is in free fall, accelerating downward at a rate of 9.8 m/s2. At the exact same time, another person throws a tennis ball out the adjacent window with a horizontal velocity of 30 m/s.

Copernicus's model of the solar system gave much better predictions than the model of Ptolemy. True or False?

What is the difference between weathering, erosion, and decomposition?

A stream of surface water reaches a porous portion of sediment and seeps into the ground this water eventually joined a large reservoir of water located beneath the earth's surface

A stretched spring has 5184 J of elastic potential energy and a spring constant of 16,200 N/m. What is the displacement of the spring?

A block of mass 1.3 kg is resting at the base of a frictionless ramp. A bullet of mass 50 g is traveling parallel to the ramp surface at 250 m/s. It collides with the block, enters it, and exits the other side at 100 m/s.

Metals are good thermal conductors - that is, when there is a temperature difference across their ends, they transfer energy very efficiently from the higher temperature end to the lower temperature end.

Some stars are so far away that their light hasn't reached Earth yet. A million years in the future, will the sources of light we see when we look up at night be the same? Why or Why not?

A sound wave travels through water. What best describes the direction of the water particles?
