# Inertia Physics

 the downward force on an object due to the earth's gravity weight an SI unit for measuring mass kilogram experimental in mechanics and made observations of the moon, Venus, sun, and Jupiter.  provided evidence to disprove many of the ancient motion concepts galielo galilei  the space that matter occupies  volume a measure of the resistance an object has to a change in its motion mass formulated the laws of motion and the law of gravity developed calculus isaac newton motion that is centered around the sun heliocentric force that results from the motion or pending motion of one surface across another and that resists that motion friction the property of an object that resists any change in its motion inertia every object continues in a state of rest, or in a state of motion in a straight line at a constant speed, unless it is compelled to change that state by forces exerted upon it  newton's 1st law motion that is centered around the earth geocentric  formulated by Galileo to explain why objects resist changes in their motion law of inertia  an SI unit for measuring force newton proposed in the early 16th century that the earth and all other planets move around the sun nicholas copernicus Authoremilyyx14 ID184652 Card SetInertia Physics Descriptionphysics Updated2012-11-20T18:08:35Z Show Answers
