P5c: Projectile Motion
1 An object PROJECTED HORIZONTALLY in the Earth's gravitation field
1.1 darts/missiles/balls
2 Path is CURVED a.k.a. TRAJECTORY
2.1 PARABOLIC
2.1.1 FASTER NEARER GROUND
2.1.2 SLOWER AT TOP
3 NEWTON'S PROJECTILE
3.1 A projectile thrown horizontally from a high point on Earth would never hit the ground if it was launched with enough speed
3.1.1 REMAIN in ORBIT above Earth
4 Horizontal Projection
4.1 A ball THROWN HORIZONTALLY from the top of a tower will fall to the ground at the same time as a ball DROPPED VERTICALLY
4.1.1 Horizontal
4.1.1.1 Acceleration=0
4.1.1.2 Time=Vertical time
4.1.1.3 HOW FAR
4.1.2 Vertical
4.1.2.1 Initial Velocity=0
4.1.2.2 Acceleration=10
4.1.2.3 Time= Horizontal time
4.1.2.4 HOW HIGH
4.1.3 EQUATIONS OF MOTION
5 Analysing Projectile Motion
5.1 AIR RESISTANCE IS IGNORED
5.2 Constant horizontal velocity
5.3 Steadily increasing vertical velocity
5.3.1 Accelerates towards the ground
6 Forces on Projectiles
6.1 When air resistance is IGNORED the force REMAINING is GRAVITY
6.1.1 ONLY affects VERTICAL VELOCITY
6.2 Accelerates downwards at 10m/s
6.3 Deccelerates at 10m/s
6.3.1 Moves upwards
