Forces and Terminal Velocity Flashcards
1
Q
The faster an object moves through a fluid…
A
The greater the frictional force that acts on it
2
Q
Terminal Velocity?
A
Constant velocity that’s reached when drag= weight, meaning resultant force= 0, and there’s no acceleration
3
Q
Initially, what does an object falling through a fluid do?
A
Accelerate due to the force of gravity
4
Q
Why do parachutes reduce terminal velocity?
A
Larger surface area causes more air to hit it, creating more drag, slowing it down
5
Q
What are the units of weight?
A
N
6
Q
What are the units of gravitational field?
A
N/Kg
