A falling object (directly downward) is slowed down by air resistance. In turn it would take longer to fall.
Here's a formula that's simple and useful, and if you're really in
high school physics, I'd be surprised if you haven't see it before.
This one is so simple and useful that I'd suggest memorizing it,
so it's always in your toolbox.
This formula tells how far an object travels in how much time,
when it's accelerating:
Distance = (1/2 acceleration) x (Time²).
D = 1/2 A T²
For your student who dropped an object out of the window,
Distance = 19.6 m
Acceleration = gravity = 9.8 m/s²
D = 1/2 G T²
19.6 = 4.9 T²
Divide each side by 4.9 : 4 = T²
Square root each side: 2 = T
When an object is dropped in Earth gravity,
it takes 2 seconds to fall the first 19.6 meters.
Speed or power activities
Answer:
No they are totally different...
Velocity is displacement/time. while vector is both magnitude and direction.....
Velocity is a vector quantity because it has both magnitude and direction
Answer:
0.5 m/s2
Explanation:
accelration formula : final velocty - starting velocity divided by time
