#3.4 u3aos1 - projectile motion Flashcards
projectile
2 marks
an airborne body
that is only affected by the forces of gravity and air resistance
projectile motion
1 mark
the movement of an object through air.
what are the two components of projectile motion
2 marks
vertical
horizontal
vertical
2 marks
hint: VC and IPV
is influenced by gravity
and the vertical component of the initial projection velocity
horizontal
2 marks
hint : HV and IPV
effected by air resistance
and the horizontal components of the initial projection velocity
three factors projectile motion depends on
3 marks
angle of release
height of release
speed of release
angle of release
4 marks
an angle at which an object is projected into the air
there are three types:
- vertical trajectory
- parabolic trajectory
- horizontal trajectory
vertical trajectory
1 mark
going traight up then back down
eg: vertical jump
parabolic trajectory
1 mark
when the angle of projection is between 0 and 90 degrees
horizontal trajectory
1 mark
an object projected at 0 degrees
speed of release
1 mark
the speed of which an object is thrown, propelled, or kicked in the air
height of release
2 marks
the difference between the height of release (where projectile is released) and
the height at which it stops or lands
what happens when the height of release is 0
2 mark
projectile height equals the landing height
optimal angle is 45 degrees
what happens when the height of release is more than 0
2 marks
projectile height is bigger than landing height
optimal angle is bigger than 45 degrees
what happens when the height of release is less than 0
2 marks
projectile height is lower than landing height
optimal angle is smaller than 45 degrees
