Front

What are the two factors that affect gravity?

Back

Mass and distance.

Front

What is a measure of gravity pulling on an object's mass?

Back

Weight.

Front

Which celestial body has the greatest effect on Earth's tides?

Back

Moon.

Front

What type of tide occurs when the sun, Earth, and the moon are nearly in a line?

Back

Spring tide.

Front

What is the amount of matter in an object called?

Back

Mass.

Front

What is the force that attracts two bodies towards each other?

Back

Gravity.

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

What is a neap tide?

Back

A neap tide occurs when the sun and moon are at right angles to each other, resulting in the lowest tidal range.

Front

How does distance affect the force of gravity?

Back

The force of gravity decreases as the distance between two objects increases.

Front

What is the gravitational force of the Earth on a 10 kg object?

Back

Approximately 98 Newtons (using g = 9.8 m/s²).
