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

Gravity

________: A force that exists between any two objects that have mass and that pulls the objects together.

Friction

________: A force that opposes the motion of a body across a surface or through a gas or liquid.

Inertia

________: An object's resistance to a change in motion.

Static Friction

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

Fluid Friction

________: Occurs between fluid layers that are moving relative to each other.

Terminal velocity

________: The maximum velocity (speed) attainable by an object as it falls through a fluid.

Air resistance

________: A type of friction, or fluid resistance, another type of friction or fluid friction.

Conservation of momentum

________: A law that states that the total momentum is conserved in a closed system.

Weak nuclear force

________: The force responsible for radioactive decay.

Strong nuclear force

________: The force that holds the nucleus of atoms together.

Force

________: A pull or push that is applied to an object.

Electromagnetic force

________: Responsible for the chemical bonds between atoms which create molecules, and intermolecular forces.

Gravitational force

________: An attractive force that occurs between all objects that have mass.

Centripetal force

________: Any force that causes centripetal acceleration.
