Females lay 2,000-4,000 eggs in small masses attached to underwater vegetation.

In the diagram a simple harmonic oscillator, comprising a mass attached to one end of a spring, is shown.

The negative sign indicates that the force is always opposing the motion of the mass attached to it:

Breeding occurs mostly after heavy rain and eggs are laid in a floating foamy mass, often attached to vegetation.

Eggs are laid in large masses attached to aquatic vegetation.

Counterweight - is a mass attached to the rear of the forklift truck frame.

When bacteria settle in, they expand and clump together, becoming a larger mass attached to your heart muscle or valve.

The basic, open-loop accelerometer consists of a mass attached to a spring.

The simplest mechanical oscillating system is a mass attached to a linear spring subject to only weight and tension.

The eggs are carried and hatched in a mass attached to the abdomen inside the shell.
