Displacement The
distance in a straight line in a certain direction from the starting point.
Velocity The speed of something in a given direction.
Acceleration
(a):
is the rate of change of velocity with time.
Gradient
is
speed of object.
Distance
(d) total length covered by a moving
object.
Displacement(s) the distance
measured in a specific direction.
Speed is
the rate of change of distance with time.
Velocity
(v) is the rate of change of displacement
with time.
Pressure is
the force acting per unit area on a body.
Energy
is
defined as the capacity to do work.
Density
is
the mass per unit volume of a substance.
Mass is
a measure of the amount of matter in an object. SI unit: kilogram (kg)
Weight is due to the pull of gravity (or, gravitational
force of attraction) upon a mass.
Power is
the rate of work done or energy converted.
Resistance is
the ratio of the potential difference across the component to the current
flowing through it.
Average
speed The average distance traveled per hour, calculated over
the whole journey, excluding specifically ordered halts.
