Science Test Preparation: Motion, Momentum, and Newton's Laws

This flashcard set covers the essential components of the GED Science exam, focusing on motion, momentum, Newton's laws of gravity and motion, and specific planetary facts about Mars.

GED science test duration

A 90-minute exam covering Earth and space science, life science, and physical science.

GED science passing score

A score of 145 or higher on a scale ranging from 100-200.

Motion

A change in position, measured by distance and time.

Law of conservation of momentum

A law stating that when two objects collide in a closed system, the total momentum before the collision is equal to the total momentum after the collision.

Newton's Law of Gravitation

The principle that everything in the universe attracts everything else, with a force that is stronger when objects are more massive.

Newton's Law of Gravity Formula

$F = G \frac{M_1 M_2}{d^2}$, representing Force equals Gravity times the product of the masses divided by the distance squared.

Newton's First Law of Motion

The law stating an object remains at rest or moves at a constant velocity unless acted upon by an external force.

Mars Surface Gravity

$0.38\,g$, which is approximately one-third of the gravity found on Earth.

Red Planet

A common name for Mars, the fourth planet from the Sun and the second-smallest planet in the Solar System.

Energy emission in collisions

Form of energy released during a collision which can include heat, sound, and sometimes light.

Scientific Reasoning Skills

The ability to use data to make conclusions, identify variables or hypotheses in experiments, and apply math in scientific settings.

GED Science Exam Topics

Reading and meaning in science, designing and interpreting science experiments, and using numbers and graphics in science.
