Gravity and Tides

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, with the strength of the force depending on the masses of the objects and the distance between them.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

Which has more mass, Earth or the Moon?

Back

Earth has more mass than the Moon.

Front

Why does the Moon have a significant effect on Earth's tides?

Back

The Moon is much closer to Earth than the Sun, making its gravitational pull stronger on Earth's oceans.

Front

What are spring tides?

Back

Spring tides occur when the Earth, Moon, and Sun are aligned, resulting in higher high tides and lower low tides.

Front

What are neap tides?

Back

Neap tides occur when the Moon is at a right angle to the Earth and Sun, resulting in lower high tides and higher low tides.

Front

What causes tides?

Back

Tides are caused by the gravitational pull of the Moon and the Sun on Earth's oceans.

Front

What is the role of the Sun in tides?

Back

The Sun also affects tides, but its effect is less than that of the Moon due to its greater distance from Earth.

Front

What is the measure of the force of gravity on an object?

Back

Weight is the measure of the force of gravity on an object.

Front

What type of tide occurs during a full moon?

Back

A spring tide occurs during a full moon.
