Projectile Motion

Kinematics

• the pattern or sequencing of movement concerning time

• the appearance of a motion

• visually observable aspects of technique or form

Linear Kinematic Quantities

movement kinematics is also referred to as from or technique

Linear displacment

• change in location

• the redirected distance from the inital to the final location

• The vector equivalent of linear distance

• measured in units of cm, m, km

Linear speed

• hindrance covered over the time taken

• speed = distance over time

• Measured in units of m/s

Running speed is the product of _____ and _____

stride length, stride frequency

Acceleration

• the rate of change in linear velocity

• acceleration = change in velocity over time

• a = v2-va/t

• measured in units of m/s

Factors influencing projectile trajectory

Relative projection height is the difference between projection height and landing height

• flight time

• horizontal dispalcemnet

• vertical displacement

• trajectory
