Physical Science Flashcard

Front

What ancient astronomer supported the idea that the Earth is spherical based on the observation of Earth's shadow cast on the Moon during a lunar eclipse?

Back

Anaxagoras

Front

What type of motion describes an object that is parallel to the ground until it falls back to the ground, involving both natural and violent motion?

Back

Projectile Motion

Front

What phase of the moon occurs during a solar eclipse?

Back

New Moon

Front

1.53

Front

What type of wave is an electromagnetic (EM) wave?

Back

Electro and Magnetic wave

Front

Define Projectile Motion.

Back

Projectile motion is the motion of an object thrown into the air, subject to the force of gravity, following a curved path.

Front

What is the Law of Inertia?

Back

The Law of Inertia states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

What is the significance of the New Moon phase in relation to solar eclipses?

Back

During a solar eclipse, the Moon is positioned between the Earth and the Sun, which occurs only during the New Moon phase.

Front

What is the formula for calculating the index of refraction?

Back

n = c/v, where n is the index of refraction, c is the speed of light in a vacuum, and v is the speed of light in the medium.

What are the two main types of waves in physics?

Back

Mechanical waves and electromagnetic waves.
