Linear Momentum (p) |
Product of mass and velocity |
|
Impulse (J or delta p) |
Change in momentum |
|
Law of Conservation of Linear Momentum |
The total momentum of an isolated system (no external forces) remains constant |
|
Work |
The product of a force on an object and the displacement of the object in the direction of force |
|
Principle of Conservation of Energy |
The total energy of an isolated system(no external forces) remains constant |
|
Elastic Collision |
A collision in which kinetic energy is conserved |
|
Power (P) |
The rate at which work is done or the rate at which energy is transferred |
|
Efficiency (η, eta) |
The ratio of the useful energy(/power/work) output to the total energy(/power/work) input |
|
Kepler's Third Law |
The ratio of the orbital period squared to the average orbital radius cubed is constant for all planets |
|
Newton's Universal Law of Gravitation |
The force of gravity between two objects is directly proportional to the product of the two masses and inversely proportional to the square of the distance between them and acts along a line joining their centers. |
|
Gravitational Strength (g) |
gravitational force per unit mass on a point mass |
|
Gravitational Potential Energy (Ep) |
The work done in moving a mass from infinity to a point in space |
|
Escape speed |
Minimum speed of a rocket needed to escape the gravitational attraction of a planet |
