gravity
True
Free FallWhy does an object fall to the ground
when dropped?GRAVITY
Gravity pulls objects towards the Earth at an acceleration 9.8 meters/sec/sec
(m/s2).
Free Fall: How Fast Elapsed time – the time that has
passed since the beginning of the fall.
In free fall, an object accelerates at a rate of 10 m per second every second
Free Fall: How FastTo calculate velocity in free fall:velocity = acceleration X time
orv=gt
Remember: g= acceleration due to gravity
But we all know the elephant would land first. Why?
Answer:
AIR RESISTANCE
Air resistance alters the motion of falling objects by adding additional forces.
