Define motion. Give 3 the laws of motion.

Definition of Motion:

A body is said to be at motion if it changes its position with respect to its surroundings.

First Law of Motion:

A body continues its state of rest or uniform motion in a staight line provided no net force acts on it.

Second Law of Motion:

When a net force acts on a body, it produces acceleration in the body in the direction of the net force.

Third Law of Motion:

To every action there is always an equal but opposite reaction.

Hope that helps...

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

i will answer your question if you answer mine
