measure of how quickly velocity changes

when a living creature puts pressure on an object

total distance traveled divided by total time traveled

a set of forces that cancel one another so that there is no overall force on an object

how far an object moves; follows entire route traveled

the change in energy from one form to another

occurs when there is no movement; forces are balanced

a push or pull that acts on an object

condition when gravity is the only force acting on an object

a force that opposes motion between objects that are touching

force that pulls all things toward the center of earth; rate of 9.8 m/s²

attraction between objects that is due to their masses; this force pulls everything to the center of the Earth and causes objects to fall

the tendency of an object to resist a change in motion

objects in motion

attraction or repulsion between two charged objects because of their motion

amount of matter in an object

average of a set of numbers

property of a moving object that depends on the object's mass and velocity

an ojects change in position relative to a reference point

a decrease in velocity and speed

an object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an unbalanced force

acceleration of an object depends on the mass of the object and the net force applied

for every action there is an equal and opposite reaction

the support force exerted upon an object which is in contact with another stable object

the location of an object

the energy of position, or energy that is stored

measure of how quickly distance changes over time

pushes an object when compressed and pulls an object when it is stretched

the constant velocity of a falling object when the size of the upward force of air resistance matches the size of the downward pull of gravity

duration an event takes place

a set of forces that do not cancel one another so that there movement

speed of an object in a particular direction

measure of the force of gravity on an object

the action that results when a force causes an object to move in the direction of the force; transer of energy measured in joules
