Studied by 2 peoplescalar quantity
Has magnitude only, eg. mass, speed, distance
vector quantity
Has both magnitude and direction, eg. weight, velocity, acceleration, force
How do you connect a resultant force triangle?
From head to tail.
moment equation
force x distance (m=fd)
moment unit
Nm
Coplanar forces
Forces lying on the same plane
Gradient of a displacement time graph?
= velocity
Gradient of a speed time graph?
= acceleration
Area under speed time graph?
The displacement of the object
Area under acceleration time graph?
= object’s change in velocity
