13) Calculate the of the object in the previous problem.

relation between the amount of a material and the space it takes up, calculated as mass divided by volume.

a quantity of space, such as the volume within a box or the volume taken up by an object.

a measurement of the amount of matter in an object made by determining its resistance to changes in motion (inertial mass) or the force of gravity applied to it by another known mass from a known distance (gravitational mass). The gravitational mass and an inertial mass appear equal.

the force of gravity on on object, typically in reference to the force of gravity caused by Earth or another celestial body

the rate at which an object changes velocity when gravity is the only force acting on the object

any interaction that causes objects with mass to change speed and/or direction of motion, except when balanced by other forces. We experience forces as pushes and pulls.

the total amount of remaining unbalanced force on an object

the state being in equilibrium (no unbalanced forces or torques) and also having no motion

a force that acts on surfaces in opposition to sliding motion between the surfaces

a graphical illustration used to visualize the forces applied to an object

the upward force exerted by any fluid upon a body placed in it

pushed out of original position, typically in reference to fluid pushed out of the way by an object placed in the fluid, or an object being displaced from its equilibrium position

the reading on a scale that is used to measure the weight of an object that is submerged in a fluid
