Cards in this deck (8)
- 1ScalarMagnitude without direction e.g. length, area, volume, distance, speed, mass, density, pressure, temperature, energy, work, power, electrical potential, charge & time.
- 2VectorA quantity that has both magnitude and direction e.g. displacement, velocity, acceleration, momentum, forces (weight), fields, a.c voltage & current when calculating fields
- 3DisplacementNet distance moved in a particular direction
- 4Instantaneous SpeedSpeed measured between two points at a very small time apart
- 5Average Speeddistance covered / time taken - distance traveled per unit time
- 6VelocitySpeed in a given direction
- 7AccelerationGradient of a velocity time graph = change in velocity per unit time taken
