2-Forces and Motion

Gravity and Motion, Newton's Laws of Motion, and Momentum- Eighth Grade Science

QuestionAnswer
At what rate do objects fall to earth? 9.8 m/s^2 (9.8 meters/second squared)
what is the mathematical equation for the velocity of falling objects? Δv = g*t
terminal velocity the constant velocity of a falling object when the force of air resistance is equal in magnitude and opposite in direction tot he force of gravity
free fall the motion of a body when only the force of gravity is acting on the body.
what is an example of an object in free fall? an astronaut in space/ a feather in a vacuum
projectile motion the curved path that an object follows when thrown, launched, or otherwise projected near the surface of the earth.
Properties of projectile motion thrown with a horizontal push accelerated downward by gravity does not accelerate horizontally
