A body has a uniform velocity in frame of reference X.Is there any other frame of reference in which the body can be at rest?

Is earth an inertial frame of reference?

What is a frame of reference? Explain inertial and non-inertial frames of reference.

The magnetic force depends on v which depends on the inertial frame of reference. Does then the magentic force differ from inertial frame to frame? Is it reasonable that the net acceleration has a different value in different frames of reference?

A charged particle moving with a uniform velocity vecv enters a region where uniform electric and magnetic fields vecE and vecB are present. It passes through the region without any change in its velocity. What can we conclude about the relative direction of vecE , vecv and vecB?

A charged particle moving with a uniform velocity vecv enters a region where uniform electric and magnetic fields vecE and vecB are present. It passes through the region without any change in its velocity. What can we conclude about the magnitude of vecE and vecB ?

Can a body have zero velocity and still be accelerated?

Draw velocity-time graph for a body moving with uniform velocity. Hence show that the area under the velocity-time graph gives the distance travelled by the body in a given time interval.
