3.3 Movement in space
LO-Discover why objects moving in space do not slow
down as they do on earth
Air Resistance- force caused by a moving object having to
push against the particles in the air.
 Acts in the opposite direction of movement.
 Faster an object moves, the greater air resistance
Vacuum-A space where there are no particles
Air resistance is zero
Application
Airplane during flights, Flaps are closed
Thereby reducing the air resistance.
Airplane during landing, Flaps are open,
the aeroplane can slow down faster with
extra air resistance
Application-Juno probe(no air resistance or vacuum)
Juno probe would have lot of air resistance if it
were to move on Earth
Juno probe when passed through Jupiter it
reached the speed of 266000km/h
Ans :1 Towards the
sun

:1 Towards the sun
Ans 2: Gravitational force of
the sun
Ans 3: Jupiter, because it has largest mass
among the planet.
Ans 4: Vacuum
