Question | Answer |
an objects change in position relative to a reference point | motion |
distance traveled divided by the time interval during which the motion occured | speed |
the speed of an object in a particular direction | velocity |
the rate at which velocity changes over time;this happens if speed, direction, or both change | acceleration |
a push or pull exerted on an object in order to change the motion of the object; has size and direction | force |
the SI unit for force (symbol N) | newton |
the combination of all the forces acting on an abject | net force |
a force that opposes motion between two objects that are in contace | friction |
a force of attraction between objects that is due to their masses | gravity |
a measure of the gravitational force exerted on an object;its value can change with the location of the object | weight |
measure of the amount of matter in an abject | mass |
constant velocity of a falling object when the force of air resistance is equal or opposite in direction to the force of gravity | terminal velocity |
motion of an obect when only the force of gravity if action in the object | free fall |
the curved path that an object follows when thrown,launched,or otherwise projected near the surface of Earth | projectile motion |
tendency of an object to resist a change in motion unless an outside force acts on the object | inertia |
a quantity defined as the product of the mass and velocity of an object | momentum |
