A.1 Kinematics Flashcards
Vector
A quantity that has both magnitude and direction
Scalar
A quantity that has only magnitude and no direction
Resultant Vector
The vector sum of two or more vectors
Magnitude
The size or length of a vector
Direction
The orientation of a vector in space
Displacement
The change in position of an object
Velocity
The rate of change of position; vector quantity
Speed
The rate of motion or the magnitude of velocity; scalar quantity
Acceleration
The rate of change of velocity
Uniform Motion
Motion at constant velocity; no acceleration
“suvat” Equations
A set of equations used to analyze uniformly accelerated linear motion
Free Fall
The motion of a body where gravity is the only force acting upon it
Uniformly Accelerated Motion
Motion where velocity changes at a constant rate
Instantaneous Velocity
The velocity of an object at a specific moment in time
Average Velocity
The total displacement divided by the total time taken
Projectile Motion
The motion of an object thrown or projected into the air, subject to only the acceleration of gravity
Maximum Height
The highest point reached by a projectile
Range of a Projectile
The horizontal distance traveled by a projectile
Time of Flight
The time for which a projectile remains in the air
Air Resistance
The force that opposes the motion of objects through air, affecting the range and maximum height of a projectile
