Question | Answer |
---|---|
forces that require that the objects touch each other | contact forces |
forces that do not require that the objects touch each other | field forces |
the combination of all forces acting on an object | net force |
force that opposes motion between two surfaces that are in contact | friction |
force that resists the initiation of sliding motion between two surfaces that are in contact and at rest | static friction |
force that opposes the movement of two surfaces that are in contact and are moving over each others | kinetic friction |
the tendency of an object to resist a change in motion unless an outside force acts on the object | inertia |
the gravitational force an object experiences because of its mass | weight |
a measure of the amount of matter in an object | mass |
the motion of a body when only the force of gravity is acting on the body | free fall |
the constant velocity of a falling object when the force of air resistance is equal in magnitude and opposite in direction to the force of gravity | terminal velocity |
the curved path that an object follows when thrown, launched, or otherwise projected near the surface of Earth | projectile motion |
quantity defined as the product of the mass and velocity of an object | momentum |
