force calculations Flashcards
force
a push or pull that tends to alter the state of motion of a body
force calculation
mass x acceleration
force units
newtons
momentum
the quantity of motion possessed by a body
momentum equation
mass x velocity
momentum units
kilogram meters per second - Kgm/S
velocity
the speed of a body in a given direction and is the rate of change of displacement
velocity calculation
displacement / time taken
velocity units
metres per second
m/s
acceleration
the rate of change in velocity
acceleration equation
V2 (final velocity) - V1 (initial velocity) / time taken
acceleration units
metres per second per second
m/s2
weight
the gravitational pull that earth exerts on a body
weight calculation
mass x acceleration
weight units
newtons
displacement
the shortest straight line route between start and finish points
displacement equation
shortest straight line route between start and finish points
displacement units
metres
