Document Summary

Speed: the rate of change of position (powerpoint, slide #11) Acceleration: the rate of change of velocity (powerpoint, slide #11: any change in speed or direction, whenever you are accelerating you feel like you are being pushed around, ex. Newton"s laws: newton"s laws apply to both earth and space, newton"s first law: an object in motion remains in motion unless acted upon by an outside force (powerpoint, slide #13) If you push against an object there is a force pushing back on you. If there is no force applied to the system, the momentum will remain the same: momentum is conserved no matter what. Angular momentum: mass times velocity times distance (mvr) (powerpoint, slide #19: angular momentum is conserved no matter what, when distance increases, velocity increases, when distance decreases, velocity increases. If the earth had less mass, we would weigh less.
