Physics Chapter 10 Test

projectile

very similar to free fall, but has a “horizontalness” to the motion we must account for

acceleration for projectile motion in the vertical direction

ay = g

acceleration for projectile motion in the horizontal direction

ax = 0

horizontal projection

initial velocity is horizontal

rane

horizontal distance

satellite

an object that orbits around another

orbit

the path an object takes around another

the total flight time of a projectile depends on the _______ direction

vertical

how are projectiles and satellites similar physically

they both follow the same path shape (parabola)

keplers first law

the orbits of the planets are elliptical, with the sun at one focus

keplers second law

the paths of the planets sweep out equal areas in equal time

keplers third law

the square of a planets orbital period is directly proportional to the cube of its distance from the sun (orbital radius)

energy - closer to earth = more _____ energy

kinetic

energy - further from earth = more ______ energy

potential

angular momentum - closer to earth = ______

faster

angular momentum - further from earth = ______

slower
