PLEASE HELP ME The force that contributed to the formation of planets, determines the motion of bodies in the solar system, and pulls objects to the center of Earth is called . The principle that states that an object at rest will stay at rest and that an object in motion will stay in motion is the law of inertia

Which articulations allow for greatest range of motion?

Photoelectrons with a maximum speed of 6.50 x 107 m/s are ejected from a surface in the presence of light with a frequency of 6.75 x 1014hz. if the mass of an electron is 9.10 x 10-31 kg, calculate in joules the maximum kinetic energy of a single electron. 3.84 x 10-15 j 1.92 x 10-15 j 5.92 x 10-23 j 3.07 x 10-16 j

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving
