Where does the maximum velocity occur?
What is terminal velocity?
How do you find the maximum velocity in a negative direction?
Why is velocity a quantity?
Terminal velocity is the maximum speed attainable by an object as it falls through a fluid (air is the most common example). It is reached when the sum of the drag force ( F d ) and the buoyancy is equal to the downward force of gravity ( F G ) acting on the object.
(mæksɪməm ) adjective [ADJECTIVE noun] B1. You use maximum to describe an amount which is the largest that is possible, allowed, or required. [...] Maximum is also a noun. [...] See full entry for 'maximum' Collins COBUILD Advanced Learner’s Dictionary. Copyright © HarperCollins Publishers. Definition of 'velocity' velocity. (vɪlɒsɪti )
Velocity is a vector close vector A physical quantity that has both magnitude (size) and direction. Eg force, velocity, displacement, acceleration. quantity because it has...
Your notion of velocity is probably similar to its scientific definition. You know that a large displacement in a small amount of time means a large velocity and that velocity has units of distance divided by time, such as miles per hour or kilometers per hour.
- You can imagine throwing a ball into the air, the ball would have an upward (positive) speed immediately after throwing, but would be slowing down...
- choose a time (t) at which you want to find the instantaneous speed. Draw a tangent to the curve at that point (t) Find the gradient of the tangent...
- Not entirely actually. Speed takes into account the entire distance travelled over a time period, while velocity is the displacement over a time pe...
- The answer is -4 because the slope is negative.

- You don't need a formula here, they tell you he went one way for 20 seconds and the the other way for 8 seconds. That's 28 seconds. If you were usi...
- Terminal velocity is reached when gravity and air resistance balance, keeping an object in free fall from accelerating.
- The video before this doesn't really explain it very well. The next video here 'Position vs. time graphs explains it much better.
Dec 14, 2020 · If acceleration is positive to the left and negative to the right, the point is a maximum velocity. In the example, a=3cos(t) is positive just before t=π /2 and negative just after, so it is a maximum; however, 3π/2 is a minimum because a=3cos(t) is negative just before 3π/2 and positive just after.
Sep 12, 2022 · The maximum velocity occurs at the equilibrium position (x = 0) when the mass is moving toward x = + A. The maximum velocity in the negative direction is attained at the equilibrium position (x = 0) when the mass is moving toward x = −A and is equal to −v max.
Terminal velocity is the maximum speed achieved by an object freely falling through a gas or liquid. At terminal velocity, the forces acting on the object are balanced so it...
