Physical Science

inertia the tendency of an object to resit a change in its motion
mass a measure of the gravitational force exerted pm an object; its value can change with the location of the object in the universe
gravity is the force of attraction between objects that is due to their masses
friction a force that opposes motion between two surfaces that are in contact
distance the extent or amount of space between two things, points, lines, etc ..
balanced force forces acting on an object that combine and form a net force of zero
unbalanced force force acting on an object that combine and form a net force that is not zero
gravitational force is a force that attracts any object with mass.
Newton's first law of motion the law that states that if the net force on an object is zero, the motion of the object does not change
net force the combination of all the forces acting on an object
velocity the speed of an object in a particular direction
acceleration the rate at which velocity changes over time; an object accelerated if its speed, direction, or both change
