Conceptual Physics 10: Projectile and Satellite Motion
trajectory
the path followed by a projectile
Period of a Satellite
the time for a satellite to make one complete revolution
55 degrees
will have the same range as a projectile fired at 35 degree
30 degrees
will have the same range as a projectile fired at 60 degrees
Vertical Component of Velocity
A vector that describes the component of a projectile's velocity that changes with gravity throughout a projectile's path
Horizontal Component of Velocity
A vector that describes the component of a projectile's velocity that remains constant through the projectile's path
Geostationary Satellite
Satellites used for communication
Polar Satellites
Satellites used for surveillance and spying
Escape Speed
The Speed that a projectile, space probe, or similar objects must reach to extricate itself from the gravitational influence of the celestial body to which it is attracted.
Range
The horizontal displacement a projectile will travel
45 degrees
maximum range of a projectile fired
Satellite
A projectile or small celestial body that orbits a larger celestial body
24 hours
Period of a geostationary satellite
90 minutes
Period of a polar satellite
28 days
Period of the moon
5 meters
distance any freely falling object travels in the 1st second of freefall
Projectile Motion
A combination of horizontal motion and a vertical gravitational pull.
Projectile
Any object that moves through the air or through space by nature of its own inertia and gravity.
Trajectory
The path that a projectile takes
Parabola
The shape of the path followed by a projectile
