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
