what is the definition of distance?
a measure of path a body takes from one position to another (miles)
is distance a scaler or vector?
scaler
what is the definition of displacement?
with reference to start and finish position
is displacement scaler or vector?
vector
what is known as speed and is it s or v?
scaler body movements per unit of time (m/s)
what is known as velocity? and is s or v ?
the rate of change of the speed of something in a given direction
vector
what is known as acceleration ? and s or v?
vector
a rate of change of the velocity measure in m/s +ve
what is known as deceleration ? s or v?
vector
rate of change in velocity -ve
what is known as mass ? s or v?
scaler
the quantity of matter a body processes
what is known as weight? s or v ?
vector
the force exerted on the mass of body by gravity
what is known as momentum ? s or v?
the amount of motion a body processes
vector
what is known as inertia?
the reluctance of a body to change its state of motion
