Front

State that the gravitational potential at a point in a gravitational field is the work done by an external force ______ in bringing unit mass from infinity to that point.

Back

per unit mass

Front

The zero of gravitational potential is taken to be at infinity.

Back

True

Front

Conservative field

Back

A field where the work done in moving a particle between two points is independent of the path taken

Front

‘Escape velocity’ is the ____________ velocity required for an object to escape a gravitational field and reach infinity.

Back

minimum

Front

Inertial reference frame

Back

An inertial frame of reference is one that is stationary or has a constant velocity.

Front

A non-inertial reference is one that is accelerating.

Back

True

Front

Einstein’s Theory of Special Relativity applies to which type of reference frames?

Back

Inertial reference frames

Front

Einstein’s Theory of General Relativity applies to non-inertial frames.

Back

True

Front

What principle describes an accelerated reference frame as being equivalent to a reference frame at rest in a gravitational field?

Back

Equivalence Principle

Front

What is a consequence of the Equivalence Principle regarding clocks in different gravitational fields?

Back

A clock in a weaker gravitational field will run faster than one in a stronger gravitational field.
