Mass x Gravity Mass x Gravity x Height Mass x 9.8 E = mc2
Satellites do not have GPE GPE is always positive The maximum value for GPE is zero. GPE is asymptotic to zero.
Delayed Human Reaction Height above sea level Air Resistance None of the Above
It is the same on all planets It is proportional to the mass of the planet It is 9.8 on earth It is proportional to the radius of the planet
It will travel the same horizontal distance if fired at 40 degrees or 50 degrees Projectiles follow a parabolic path The maximum range of a projectile is acquired by firing at 45 degrees to the horizontal All of the above
Projectiles follow a parabolic path A cannon ball and a feather would reach the ground at the same time in a vacuum Horizontal and vertical components of projectile motion occurred independently of one another but simultaneously If a projectile is fired at a high enough velocity it will escape the gravitational field of a planet and begin to orbit
To take advantage of the spin of the earth and receive a velocity boost To avoid the Van Allen radiation belts So as to not launch towards the sun So astronauts are not subjected to the 'g' forces that occur when launching East to West
Water Cannons A re-entry degree between 5.2 and 7.2 degrees Television Communication with Houston

Tension on a string that is being swung with a weight on the end Friction between tyres and the road on a corner Spin on a sliced golf ball Gravitational pull on a satellite
They orbit between an altitude of 250km and 1000km They orbit above the Van Allen radiation belts They take about 90 minutes to complete an orbit They are used to survey the surface
There is a geostationary satellite above Sydney They orbit perpendicular to the equator They orbit at the upper limits of the Van Allen radiation belts They complete an orbit in 12 hours
The Universal Gravitational Constant Radius of the orbit Mass of the planet being orbited Mass of the satellite

It permeated all matter It had high density It was luminiferous It was invisible
The movement of the earth through the aether would create an aether wind The aether should bend light Einstein had said it would work The Speed of Light in a vacuum
Galilean Relativity Newtonian Relativity Special Relativity Einstein's Relativity
Space becomes relative Time becomes relative Speed of light becomes constant Both a & b
