P5c: Projectile
Motion
- An object PROJECTED
HORIZONTALLY in the
Earth's gravitation field
- darts/missiles/balls
- Path is
CURVED a.k.a.
TRAJECTORY
- PARABOLIC
- FASTER NEARER
GROUND
- SLOWER AT TOP
- NEWTON'S PROJECTILE
- A projectile thrown horizontally from a high
point on Earth would never hit the ground if
it was launched with enough speed
- REMAIN in ORBIT above Earth
- Horizontal Projection
- A ball THROWN HORIZONTALLY
from the top of a tower will fall to
the ground at the same time as a
ball DROPPED VERTICALLY
- Horizontal
- Acceleration=0
- Time=Vertical
time
- HOW FAR
- Vertical
- Initial Velocity=0
- Acceleration=10
- Time= Horizontal time
- HOW HIGH
- EQUATIONS OF MOTION
- Analysing
Projectile
Motion
- AIR
RESISTANCE
IS IGNORED
- Constant horizontal
velocity
- Steadily
increasing
vertical
velocity
- Accelerates
towards the
ground
- Forces on Projectiles
- When air resistance is
IGNORED the force
REMAINING is GRAVITY
- ONLY affects
VERTICAL
VELOCITY
- Accelerates
downwards
at 10m/s
- Deccelerates
at 10m/s
- Moves upwards
