Gravity, Motion, and Tides (Chapter 5 Test)

Front

What is the force that attracts a body toward the center of the earth?

Back

Gravity

Front

True or False: A spring tide occurs when the Sun, Moon, and Earth are lined up.

Back

True

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object.

Front

What holds the planets in Earth's solar system together?

Back

Gravity

Front

What is Newton's first law of motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What causes tides on Earth?

Back

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

Front

What is a spring tide?

Back

A spring tide is a tide that occurs when the Sun, Moon, and Earth are aligned, resulting in higher high tides and lower low tides.

Front

What is a neap tide?

Back

A neap tide is a tide that occurs when the Sun and Moon are at right angles relative to Earth, resulting in lower high tides and higher low tides.

Front

What is the relationship between mass and weight?

Back

Weight is the product of mass and the acceleration due to gravity (Weight = Mass x Gravity).
