Gravitation/Momentum

All massive objects

All massive object attract each other with a gravitational force

F_g is equal to

F_g is equal to G times mass 1 times mass 2 divided by d²

The gravitational field g is near an object of M mass is given by

The gravitational field g is near an object of M mass is given by G times M divided by d²

in mg g is equal to

in mg g is equal to gravitational field

Gravitational mass is measured by:

Gravitational mass is measured by measuring an objects weight using weight equals mg

Inertial mass is equal to

Inertial mass is equal to net force

in all experiments ever preformed

in all experiments ever preformed gravitational mass is equal to inertial mass

momentum is equal to

momentum is equal to mass times velocity

the units of momentum are

the unites of momentum are N*s

A system’s center of mass

A system’s center of mass obeys Newton’s second law: that is, the velocity of the center of mass only changes when an external net force acts on the system

The location of the center of mass x_cm is determined by

the location of the center of mass x_cm is determined by M_tot X_cm = m₁ x₁ + m₂ x₂ …

Impulse, J is equal to

change in an objects momentum, Ft

Impulse has units of

Impulse has units of M*s

Impulse is the area of

Impulse is the area under a force vs. time graph
