Kinematics
-the study of motion
Motion
-a change in an object's location as measured by a particular observer
Distance (d)
-the total length of the path travelled by an object in motion
Direction
-the line an object moves along from a particular starting point
Scalar
-a quantity that has only magnitude (size)
Vector
-a quantity that has magnitude (size) and direction
Position (⇾d)
-the distance and direction of an object from a reference point
Displacement (Δ⇾d)
-the change in position of an object
Vector Scale Diagram
-a vector diagram drawn using a specific scale
Directed Line Segment
-a straight line between two points with a specific direction
Average Speed (v
_{av}
)
-the total distance travelled divided by the total time taken to travel that distance
Average Velocity(⇾v
_{av}
)
-the total displacement, or change in position, divided by the total time for that displacement
Position Time Graph
-a graph describing the motion of an object, with position on the vertical axis and time on the horizontal axis
Slope (m)
-a measure of the steepness of a line
m=rise/run
Motion With Uniform Or Constant Velocity
-motion of an object at a constant speed in a straight line
Motion With Non-Uniform Velocity (Accelerated Motion)
-motion in which the object's speed changes or the object does not travel in a straight line
Determining Types Of Motion From A Position Time Graph
Acceleration (⇾a
_{av}
)
-how quickly an object's velocity changes over time (rate of change of velocity)
Velocity Time Graph
-a graph describing the motion of an object, with velocity on the vertical axis and time on the horizontal axis
Motion With Uniform Acceleration
-motion in which velocity changes at a constant rate
Instantaneous Velocity (⇾v
_{inst}
)
-the velocity of an object at a specific instant in time
How To Go From A D-T Graph To A V-T Graph
How To Go From A V-T Graph To A D-T Graph
How To Go From A V-T Graph To A A-T Graph
Acceleration Time Graph
-a graph describing motion of an object, with acceleration on the vertical axis and time on the horizontal axis
Comparing Linear Motion Graphs
Uniform Acceleration Equations (5) & How To Use Them
Acceleration Due To Gravity (g)
-the acceleration that occurs when an object is allowed to fall freely; close to Earth's surface, g has a value of 9.8m/s
^{2}
Free Fall
-the acceleration due to gravity of an object in the absence of air resistance
Terminal Velocity
-the velocity of an object when the force due to air resistance equals the force due to gravity on the object
