global warming definition. The term attached to the notion that the Earth's temperature is increasing due to the greenhouse effect. Note: Whether global warming is actually happening is a subject of scientific debate.
Like jet airplanes, space rockets work on a principle called action and reaction (another name for Newton's third law of motion). The massive force (action) generated by hot gases firing backward from a rocket's engines produces an equal force (reaction) that pushes the rocket forward through space.
When the aircraft is on an East or West heading, acceleration or deceleration of the aircraft causes the compass card to tilt forward or backward, respectively. This tilting causes the compass card magnets to swing downward toward the earth, which in turn causes the compass to rotate to an incorrect indication.
