What is One Dimension (1D)
A straight line in any direction (north, south, west, east).
What is the difference between a scalar and a vector?
A scalar quantity only contains magnitude (EX: speed), while a vector quantity contains both magnitude and direction (EX: velocity). Positive directions include north and east, and negative directions include south and west.
What is the equation for time?
Final Velocity-Initial Velocity/Acceleration
What is Kinematics?
Kinematics is derived from the greek word Kinema, meaning motion. It is the study of motion, objects, and groups of objects without considering the causes of its motion.
What is the difference between fast and slow?
Fast is when something covers a long distance in a short amount of time. Slow is when something covers a short distance in a long amount of time.
What is the equation for acceleration?
Final Velocity-Initial Velocity/Time
What is speed?
Speed is the distance traveled divided by the time it took to travel that distance. Speed is also referred to as initial speed or average speed.
Speed = Distance/Time (S=D/T)
What is distance?
Distance is a scalar quantity that refers to how much ground an object has covered during its motion.
Distance = Speed x Time (d=st)
What is the equation for slope?
The equation for slope is displacement/time.
What is acceleration?
The change in velocity of an object. (Also referred to as 'how much time').
What is displacement?
Displacement is a vector quantity that refers to hoe far your ending point is from your starting point.
Displacement = Final Position - Initial Position.
What is the equation for final velocity?
Initial Velocity + Acceleration x Time.
What is slope?
Slope is another word for velocity.
What is velocity?
Velocity is the ratio of displacement and time. It is a vector quantity.
Velocity = Final Position-Initial Position/Time, Velocity = displacement/time
What is the equation for initial velocity?
Velocity Final - Acceleration x Time.
