					MOMENTUM, IMPULSE and PRESSURE

Momentum
Inertia in motion “bashing power”

(momentum = mass of object x speed)

objects at rest have no momentum since speed = 0 large momentum is the result of large mass or high speed

Impulse

How long it takes an object to change its momentum

Impulse = force applied x time force it applied

PRESSURE
Force applied by an object over a certain area Applying more force over the same area will increase the pressure Applying the same force over a larger area will decrease the pressure Units for pressure are Pascals (Pa)
