Inertia Physics

the downward force on an object due to the earth's gravity

an SI unit for measuring mass

experimental in mechanics and made observations of the moon, Venus, sun, and Jupiter.  provided evidence to disprove many of the ancient motion concepts

the space that matter occupies 

a measure of the resistance an object has to a change in its motion

formulated the laws of motion and the law of gravity developed calculus

motion that is centered around the sun

force that results from the motion or pending motion of one surface across another and that resists that motion

the property of an object that resists any change in its motion

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 

motion that is centered around the earth

formulated by Galileo to explain why objects resist changes in their motion

an SI unit for measuring force

proposed in the early 16th century that the earth and all other planets move around the sun
