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
🗑
|
||||
newton's first law of motion | an object at rest stays at rest, and an object in motion remains in motion at a constant speed unless acted on by an unbalanced force.
