IB PHYSICS Topic 6: Circular Motion and Gravitation

The line in space around which an object rotates.

A coordinate system that uses the distance from a point to an axis of rotation (r) and the angle between the position vector and the x-axis (θ) to define the position of a point in circular motion.

The rate at which the angle of rotation changes over time.

The rate at which the angular velocity changes over time.

The acceleration of an object moving in a circle, directed towards the center of the circle.

The acceleration of an object moving in a circle, directed along the tangent to the circle.

The force that causes an object to move in a circular path, directed towards the center of the circle.

An apparent force that seems to push objects away from the center of rotation in a rotating frame of reference.

The unification of the physics governing celestial and terrestrial objects, applying the same physical laws to both.

Newton's law that states that every particle in the universe attracts every other particle with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them.

Three laws of planetary motion discovered by Johannes Kepler, describing the path and motion of planets around the Sun.

A region in which an object with mass experiences a force due to gravity.

The measure of the gravitational force experienced by an object per unit mass.

Anomalies or deviations in the strength of the gravitational field within a specific area, which can be caused by geological features, underground structures, or other factors.

Details regarding the equipment or instruments used to measure the gravitational field, such as gravimeters, accelerometers, or specialized devices.

Observations or measurements related to how the gravitational field strength changes over time, which can be influenced by factors like tides, seasonal variations, or other phenomena.

Comparing collected data with existing records or models of the gravitational field for the same region to validate measurements and identify any discrepancies.

Speculation or discussion on how the observed gravitational field might impact various applications, such as geophysics, navigation, or space exploration.

Additional relevant observations that might affect or be affected by the local gravitational field, including phenomena like subsidence, seismic activity, or magnetic anomalies.

The force experienced by an object with mass (m) due to the gravitational field, which is equal to the product of mass and gravitational field strength (F = mg).

Representations of force fields, including the gravitational field, using lines to depict the direction and strength of the field.
