What is the definition of a vector?
a quantity having direction as well as magnitude, especially as determining the position of one point in space relative to another.
What is the definition of a scalar
A quantity having only magnitude, not direction.
What is the definition of displacement
the distance moved in a straight line, in a given direction, from the starting point
What is the definition of velocity
the speed in combination with the direction of motion of an object
What is resultant force?
A single force that has the same effect as all the forces combined
Distance = ?
Speed x time
Energy = ?
Potential difference x charge
Charge = ?
Current x time
Momentum = ?
Mass x velocity
Wavespeed = ?
Frequency x wavelength
Potential difference = ?
Current x resistance
