Forces & Dynamics

a resistive force between stationary objects due to the roughness of the two surfaces in contact

An object in motion stays in motion, unless acted on by a force. An object at rest stays at rest unless acted on by a force.

Force is the product of mass and acceleration.

For every action force, there is an equal but opposite reaction force.

a law that states that the total momentum is conserved in a closed system

friction that acts on objects when they are sliding over a surface

the amount of matter in an object

any force that causes centripetal acceleration

an attractive force that occurs between all objects that have mass

the force of gravity on an object

a force that opposes the motion of a body across a surface or through a gas or liquid

an object's resistance to a change in motion

the force that resists motion either within the fluid itself or of another medium moving through the fluid

the force that holds the nucleus of atoms together

a pull or push that is applied to an object

the resulting force determined by combining all of the forces acting on an object

steady speed achieved by an object freely falling through a gas or liquid

the motion of an object thrown (projected) into the air

the frictional force that occurs when one object rolls on another

a force that exists between any two objects that have mass and that pulls the objects together. The greater the mass of an object, the greater its gravitational pull.

the force responsible for radioactive decay

a quantity of how much inertia a dynamic object has

The fundamental force associated with electric and magnetic fields

a force that is caused by air

the three fundamental laws Isaac Newton discovered governing the motion of objects
