1.4 GRAVITATION Flashcards
Motion
suvat
the path of the projectile symmetrical so
initial vertical velocity = -final vertical velocity
the time of light (projectile)
2 the time to the highest point
The vertical velocity at the highest point
is zero
horisontal distance is also
known as the range
Free fall
Initially, the forces are unbalanced but with time the forces become balanced and the object fall with consant velocity,** terminal velocity**
Satellite’s orbit as an Application of projectiles
the trown ball may become the satellite if it has enough vertical velocity and great height

whem Hydrogen will be used the star will colapse
The ‘Slingshot Effect’
in which some ‘free’ ENERGY to Accelerate spacecraft
