QuestionAnswer
Force can have different magnitudes, and in different directions. a vector quantity.
Strong-force holds the nucleus of an atom together. must be very close to be significant. strong but very short range.
Electromagnetic-force holds atoms and molecules together, repel if too close. Caused by electric charges, and have infinite range.
Week-force responsible for radioactive decay. very short range
Force-of-gravity attracts due to their mass, weakest of the four forces. Infinite range
normal-force a force that is perpendicular to this common surface
friction a force that acts parallel to the common surface of contact, resisting motion between the two surfaces
field influence on a suitable object over a region of space
test mass a mass too small to measurably affect the gravitational field
weight force of gravity acting on the object
mass scalar that related to the quantity of matter an object contains
Inertia a property that resists a change in motion such as acceleration or deceleration
Newton's-First-Law An object will continue either being at rest or moving at constant velocity unless acted upon by an external non zero net force.
