Front

What is the effect of gravity on the movement of Earth through space?

Back

Without the influence of gravity from the Sun and surrounding planets, Earth would move in a straight line.

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves, such as the energy transferred from the Sun to Earth.

Front

What is an elliptical orbit?

Back

An elliptical orbit is an oval-shaped path that a planet follows around the Sun, with varying distances from the Sun.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What factors determine the gravitational pull of a planet?

Back

The gravitational pull of a planet is determined by its mass and the distance from other objects.

Front

What happens to thermal energy in solids during radiation?

Back

In solids, thermal energy can be transferred through conduction, but radiation primarily occurs in fluids and through electromagnetic waves.

Front

How does the distance from the Sun affect a planet's orbit?

Back

The distance from the Sun affects the strength of gravitational pull, influencing the shape and speed of a planet's orbit.

Front

What is the relationship between mass and gravitational force?

Back

The greater the mass of an object, the stronger its gravitational pull on other objects.

Front

What is the difference between conduction and convection?

Back

Conduction is the transfer of heat through direct contact, while convection is the transfer of heat through the movement of fluids.

Front

What is the significance of the Sun's gravity in the solar system?

Back

The Sun's gravity keeps the planets in orbit around it, preventing them from drifting into space.
