Výrazy
gravitational attraction
1/ɡɹˌævɪtˈeɪʃənəl ətɹˈækʃən/
fixed phrase
technical
mutual pull between masses
the way two masses pull toward each other.
Příklady
- Gravitational attraction between the planets slightly changes their orbits over time.
- Even small bodies exert gravitational attraction on each other.
- The simulation modeled gravitational attraction across the entire system.
gravitational constant
1/ɡɹˌævɪtˈeɪʃənəl kˈɑnstənt/
fixed phrase
technical
constant G in gravity equations
a number used in formulas to calculate gravity.
Příklady
- The gravitational constant, G, is needed to compute the force between two masses.
- Measuring the gravitational constant precisely is surprisingly difficult.
- Their model used the accepted value of the gravitational constant.
gravitational field
1/ɡɹˌævɪtˈeɪʃənəl fˈild/
fixed phrase
technical
region where gravity acts
the area around something where gravity pulls objects.
Příklady
- A planet creates a gravitational field that extends far into space.
- The astronaut moved into a weaker gravitational field as the ship climbed.
- Physicists describe the gravitational field using equations rather than direct measurement of 'pull' everywhere.
gravitational force
1/ɡɹˌævɪtˈeɪʃənəl fˈɔɹs/
fixed phrase
technical
force of attraction between masses
the force that makes two masses pull toward each other.
Příklady
- The gravitational force between the Earth and the Moon keeps the Moon in orbit.
- At that distance, the gravitational force is extremely small but not zero.
- Their calculation compared gravitational force with electrical force.
gravitational lensing
1/ɡɹˌævɪtˈeɪʃənəl lˈɛnsɪŋ/
fixed phrase
technical
bending of light by gravity
when gravity bends light like a lens.
Příklady
- Astronomers used gravitational lensing to study a very distant galaxy.
- The cluster’s mass produced strong gravitational lensing, creating arcs of light.
- Gravitational lensing can reveal the presence of dark matter.
gravitational potential energy
1/ɡɹˌævɪtˈeɪʃənəl pətˈɛnʃəl ˈɛnɚd͡ʒi/
fixed phrase
technical
energy from an object’s height
energy an object has because it is high up.
Příklady
- When you lift a book, you increase its gravitational potential energy.
- As the roller coaster climbs, it stores more gravitational potential energy.
- The system converts gravitational potential energy into kinetic energy as the object falls.
gravitational pull
1/ɡɹˌævɪtˈeɪʃənəl pˈʊl/
fixed phrase
technical
the attracting force of gravity
the force that pulls things because of gravity.
Příklady
- The moon's gravitational pull causes ocean tides on Earth.
- Farther from Earth, the spacecraft felt less gravitational pull.
- A black hole has such strong gravitational pull that even light cannot escape.
gravitational waves
1/ɡɹˌævɪtˈeɪʃənəl wˈeɪvz/
fixed phrase
technical
ripples in spacetime from gravity
very small waves in space caused by big events in the universe.
Příklady
- The observatory announced the first direct detection of gravitational waves.
- Two colliding black holes can produce powerful gravitational waves.
- The signal was so faint that researchers needed extremely sensitive instruments.
