You may not feel it. - Force The sum of all forces acting on an object - Net force Term for forces that combine to produce a net force of 0 - balanced forces An object in motion remains in motion unless acted on by a net force - Newton's first law The tenancy to keep the same motion/velocity or remain at rest. Newton's first law - inertia Net force = mass x acceleration (F = ma) - Newton's second law When one object exerts a force on a second object, the second object exerts a force of the same magnitude in the opposite direction on the first object ("For every action, an equal and opposite reaction") - Newton's third law The force that opposes the motion of an object on which it acts - friction Friction between two objects moving against each other - Kinetic friction Friction between two objects touching but not moving against each other - Static friction Friction when an object moves through a gas or liquid - Fluid resistance Attractive force between objects directly proportional to their masses and inversely proportional to the square of their distance - Gravity Name for the mass of an object times its velocity - Linear momentum Term for the fact that momentum is conserved when two or more objects collide - Law of conservation of momentum The amount of bounce an object has after a collision - elasticity
