U1L4b - Acceleration Due to Gravity Near the Earth's Surface Flashcards
1
Q
What is the definition of “acceleration due to gravity”?
A
the acceleration that occurs when an object is allowed to freely fall; close to Earth’s surface, gravity has a value of 9.81 m/s^2
2
Q
What is the definition of “free fall”?
A
the acceleration due to gravity of an object in the absence of air resistance or any other forces
3
Q
What is the definition of “terminal velocity”?
A
the velocity of an object when the force due to air resistance equals the force due to gravity on the object
4
Q
What is the value of gravity (g)?
A
9.81 m/s^2
