physics chapter 10 test – Flashcards

according to keplers laws,the paths of planets about the sun are?

a rock is thrown upward @ 50 degrees with respect to the horizontal.as it rises,neglecting air drag,it's vertical component of velocity?

a rock is thrown upward at 50 degrees with respect to the horizontal.as it rises,neglecting air drag,it's horizontal component of velocity?

a bullet fired horizontally from a rifle begins to fall?

an earth satellite is simply a projectile?

earth satellites are typically more than 100 km high so as to be above earths?

a projectile is launched at ground level an angle of 15 degrees above the horizontal and lands down range.what other projection angle for the same speed would produce the same down range distance?

two projectiles are fired from ground level at equal speeds but different angles.one fired at an angle of 30 degrees and the other at 60 degrees.the projectile to hit the ground first will be the one fired at (neglect air resistance)

without air resistance,a projectile fired horizontally at 8 km/s from atop a mountain would?

planets would crash into the sun if it weren't for there?

The circular path of a satellite orbiting the earth is characterized by a constant?

an Earth satellite is in an elliptical orbit. The satellite travels fastest when it is?

The speeds of the planets about the sun depend on?

A vertically oriented rocket that is somehow able to maintain a continuous upward velocity of 8 km/s will?

satellite in an elliptical orbit travel at constant?

The period of a satellite, the time it takes for a complete revolution, depends on the satellites?

compared to the period of satellites in orbit close to the earth, the period of satellites in orbit far from the earth is?

acceleration is greater for a satellite when it is at the?

The tangential velocity of an Earth satellite and it's velocity?

what prevents satellite such as the space shuttle from falling?

The fastest moving planet in the solar system is?

it takes Pluto a longer time to orbit the sun than the earth does because Pluto?

A "weightless" astronaut and orbiting shuttle is?

considering mood not Orbitz one of our most distant planets in an elliptical path. The distance that the moon covers each day is?

A lunar month is about 28 days if the moon were farther from the earth that it is now, the lunar month would be?
