Motion and Stability: Forces and Interactions
- Physics
Scientists Say: Force
When an object experiences a force, its change in motion — or acceleration — depends on its mass.

Teens’ new tech would send alerts to reduce preventable deaths
A trio of teen innovations created devices that can speed up the response time to pool accidents, overheating in cars and combat-related injuries.
- Physics
Scientists Say: Inertia
Inertia is the tendency of objects to resist changes in their motion.
- Earth
A new clock shows how gravity warps time — even over tiny distances
This clock measured how gravity changes the passage of time in different places — even spots just one millimeter apart.
- Animals
Orb-weaving spiders use their webs like external eardrums
Scientists discover that orb-weaving spiders listen with their legs, detecting sound vibrations that travel through their silken webs.
- Materials Science
Scientists Say: Silicone
Silicone is a generic term for a whole slew of humanmade polymers with many different forms and applications.
- Brain
Warning! Nicotine poses special risks to teens
Even a single dose of nicotine during early teen years can start a life-long cycle of nicotine use and addiction.
