If an object is dropped, how fast will it be moving after falling #3 m#?
The velocity after falling 3m would be
If drag is ignored.
All objects in free fall near the Earth's surface and with no drag have a constant acceleration of
State data and select equation:
Substitute values into the equation:
The reason for an acceleration of
Where g is the gravitational field strength. Near the Earth's surface the value of g* is
Newton's second law tells us that resultant force is equal to the product of mass and acceleration:
Combine the two equations:
Mass cancels out to leave:
