Biomechanical Calculations Flashcards
What is the definition of velocity?
Velocity is the rate of change in displacement
Or
The shortest straight-line route between start and finish
How do you calculate velocity?
Velocity=displacement/time taken
What is velocity measured in?
M/s
Because displacement is measure in metres (m)
And
Time taken is measured in seconds (s)
What is the definition of momentum?
Momentum is the quantity of motion possessed by a moving body
How do you calculate momentum?
Momentum = mass x velocity
What is momentum measured in?
Kgm/s
Because mass is measured in (kg)
And
Velocity is measured in (m/s)
What is the definition of acceleration?
Acceleration is the rate of change in velocity
How do you calculate acceleration?
Acceleration=(final velocity - initial velocity) / time taken
What is acceleration measured in?
M/s/s
Because acceleration is the change in velocity which is measured in (m/s) and time taken in seconds is (s)
What is the definition of force?
Force is a push or pull that alters the state of motion of a body
How do you calculate force?
Force = mass x acceleration
F =ma
What is force measured in?
Force = Newtons (N)
Because
Mass = Kilograms (kg)
Acceleration = Metres per second per second (m/s/s)
