GED® Science: Forces and Motion (Deep Dive)
A Physical Science deep dive into pushes and pulls, net force, inertia, Newton's laws, gravity, friction, acceleration, speed, and reading motion graphs.
📚 Course Curriculum
A force is a push or pull. Forces can start motion, stop motion, speed something up, slow it down, or change direction. The important idea …
Open trial session →Newton's First Law says an object at rest stays at rest, and an object in motion keeps moving at constant velocity, unless acted on by …

Newton's Second Law connects force, mass, and acceleration:. [[figure:newton_second_law The same push gives less acceleration to a heavier object and more acceleration to a lighter …
Open trial session →Newton's Third Law says every action force has an equal and opposite reaction force. A rocket pushes exhaust gas down; the gas pushes the rocket …
Open trial session →Speed is distance divided by time:. Acceleration is a change in velocity, which can mean speeding up, slowing down, or changing direction. Reading motion data …
