Kinematics Flashcards
Acceleration
The rate at which velocity changes over time
Acceleration due to gravity
The acceleration of an object due to its attraction to a large body (Earth, Moon, etc.)
Average speed
The total distance divided by the time interval during which the distance was traveled
Average velocity
The total displacement divided by the time interval during which the displacement occurred
Trajectory
The path of a projectile
Constant acceleration
When velocity changes by the same amount during each interval of time
Constant velocity
Constant speed and constant direction
Displacement
The net change in position of an object including direction
Distance
How far an object has moved
Vector
A quantity that has both magnitude and direction
Frame of reference
A system for specifying the precise location of objects in space and time
Free fall
The motion of a body when only the force due to gravity is acting on it
Instantaneous velocity
The velocity of an object at some instant or at a specific point in the object’s path
Magnitude
Reporting just the value in an answer (without a direction)
Vector resolution
Determining the length and direction of a vector given its components
