1

Gravitational Field

A region where a small test mass experiences a force due to another mass.

New cards
2

Electrostatic Field

A space where a small positive test charge experiences a force per unit charge.

New cards
3

Electric Potential

Given by electric potential difference (voltage) and represents the capacity for doing work by a change in position of the positive test charge.

New cards
4

Gravitational Potential

The work done per unit mass required to move a test mass from infinity to a point P in a gravitational field. It is always negative, with the potential at infinity being zero.

New cards
5

Field Lines

Show the path a test particle would take in a force field, revealing its direction and strength.

New cards
6

Equipotential Surfaces

Points with the same gravitational potential, forming surfaces. Field lines are normal to equipotential surfaces, and the density of field lines is proportional to field strength.

New cards
7

Electric Potential Energy

The capacity for doing work by a change in position of a positive test charge, given by Coulomb's constant, fixed charge, test charge, and radius.

New cards
8

Gravitational Potential Energy

The work done required to move an object from infinity to a point P in a gravitational field. It is always negative.

New cards
9

Potential Gradient

The change in gravitational potential per unit distance, related to gravitational field strength. It represents the slope of a graph plotting gravitational potential against distance from the mass.

New cards
10

Potential Difference

The work done by moving a positive test charge between two points in an electric field. It is required for current flow and is provided by cells or batteries.

New cards
11

Escape Speed

The minimum speed needed for an object to reach infinity from a planet's surface. Objects launched at or above escape speed won't return due to gravity.

New cards
12

Orbital Motion

Motion of an object in a circular path around another object, with gravitation providing the centripetal force.

New cards
13

Orbital Speed

The speed of an object in orbit, given by (GM/r)^0.5, where G is the gravitational constant, M is the mass, and r is the radius.

New cards
14

Orbital Energy

The sum of kinetic energy and gravitational potential energy for an orbiting satellite.

New cards
15

Inverse-Square Law

The behavior where the strength of a field decreases with the square of the distance from the source.

New cards
16

Inverse-Square Law Graphical Representation

Graphical representation of the inverse-square law behavior for gravitational and electric fields.

New cards
17

Gravitational Field

Graphical representation of the gravitational field in accordance with the inverse-square law.

New cards
18

Electric Field

Graphical representation of the electric field in accordance with the inverse-square law.
