Electromagnetic field, a property of space caused by the motion of an electric charge. A stationary charge will produce only an electric field in the surrounding space. If the charge is moving, a magnetic field is also produced. An electric field can be produced also by a changing magnetic field.
By using ramps you can easily push or pull the object up the ramp.
Using Newton's Second Law, we can find the air resistance. We know the net force is equal to mass times acceleration.
