- scalar and vector quantities
- scalar quantities: a physical quantity that can be measured. it has magnitude or size
- - temperature, mass, energy, distance, speed, density
- these quantities can be added and subtracted just as normal numbers eg 7kg + 4kg = 11kg
- vector quantities: both direction and magnitude
- - forces, displacement, velocity, acceleration, momentum
- forces calculations: forces acting in the same direction = sum of forces
- - forces, displacement, velocity, acceleration, momentum
- scalar quantities: a physical quantity that can be measured. it has magnitude or size
