1.4 Projectiles And Gravitation Flashcards
What is c (eg- 0.45c)
The Percentage of the Speed of Light (3x10⁸ m/s)
What is Length Dilation
What is Time Dilation
The difference in a time interval as measured by a stationary observer and a moving observer.
What is t
The proper time Frame Measured by the clock in the object’s Reference Frame. (Not observer)
What is t’
The dilated Time measured by an observer, not on the object’s Reference Frame
What is 𝓵
The proper Length measured by the observer in the reference Frame (The Actual Length)
What is 𝓵’
The contracted length as measured by an observer NOT in the reference frame of the object.
What is Newton’s law of universal gravitation
Mass attracts other Masses directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Equation to Find Gravitational Force
F = Gm₁m₂
———-
r²
What happens to Force when a mass of an object is doubled.
Force is Doubled (x2)
What happens to Force when mass of an object is halved
Force is Halved (1/2)
What happens to Force when Radius is Doubled
Force is Quartered (1/4)
What happens to Force when Radius is Halved
Force is Quadrupled (x4)
Equation to Find Vertical in Symmetric Projectiles
s = 0 m
u = Initial Vertical Velocity
v = Final Vertical Velocity
a = - 9.8 m/s²
t = Full Time of Flight / 2
Equation to Find Horizontal in Symmetric Projectiles
s = Horizontal Distance
t = Full Time of Flight
u = Initial Horizontal Velocity
