Vocabulary flashcards covering key terms and definitions related to velocity, acceleration, and motion under gravity.
Velocity-time graph
A graph that shows how velocity is related to time.
Instantaneous acceleration
The change in velocity of an object at an instant of time.
Acceleration
The rate at which an object's velocity changes.
Free fall
The motion of falling objects when air resistance is negligible.
Average acceleration
The change in velocity of an object during some measurable time interval divided by that time interval.
Acceleration due to gravity
The acceleration of an object in free fall that results from the influence of Earth's gravity.
