The constant speed that a freely falling object reaches when the resistance of the medium prevents further acceleration.

The constant speed that a freely falling object reaches when the resistance of the medium prevents further acceleration.

Terminal velocity

The force pulling an object downward due to Earth's gravity, calculated by Fgrav = mg.

Gravitational Force

The minimum speed required for an object to escape the gravitational pull of a planet.

Escape Velocity

A device consisting of a mass attached to a string that swings back and forth.

Simple Pendulum

Describes the behavior of springs; states that the force needed to stretch or compress a spring is proportional to the distance stretched/compressed.

Hooke's Law

The force that resists the start of motion between two surfaces in contact.

Static Friction

The force that opposes the relative motion of two surfaces sliding against each other.

Kinetic Friction

The force that resists the motion of a rolling object over a surface.

Rolling Friction

The force that opposes the motion of an object through a fluid.

Fluid Friction

The overall force acting on an object when all individual forces are combined.

Resultant Force

The amount of matter in an object measured in kilograms.

Mass

The force of gravity acting on an object, measured in Newtons (N).

Weight

The constant used in gravitational force calculations, approximately 6.67 x 10^-11 N m²/kg².

Gravitational Constant (G)

Planets orbit in elliptical paths with the Sun at one focus.

Law of Orbits (Law of Ellipses)

Planets move faster when closer to the Sun and slower when farther away, sweeping out equal areas in equal times.

Law of Areas (Law of Equal Areas)

Planets farther from the Sun take longer to orbit than those closer.

Law of Periods (Law of Harmonies)
