Unit 1 - Projectile Motion Flashcards
What is a projectile?
An object moving under the influence of gravity.
What acceleration does gravity cause on all objects?
9.8 m/s².
Is the horizontal speed of a projectile constant?
Yes
What equation is used for horizontal motion of a projectile?
d = v × t
What controls the vertical motion of a projectile?
The force of gravity.
What is the equation for vertical acceleration?
a = (v - u) ÷ t
What is the equation to calculate final vertical speed?
v = u + a × t
What is the vertical speed when a projectile is kicked horizontally?
Initial vertical speed u = 0 m/s
How do you calculate time of flight?
t = (v - u) ÷ a
How far does a projectile travel horizontally?
distance = horizontal speed × time
What happens to the projectile path with more speed?
It curves further and may go beyond the horizon.
What is satellite motion?
A projectile moving so fast it falls around Earth’s curvature.
What is free fall in orbit?
Constant falling due to gravity while moving forward horizontally.
How high does the ISS orbit?
Approximately 350 km above Earth.
How long does a geostationary satellite take to orbit?
24 hours.
