Although the name implies an upward force, lift can push a ball toward one side or the other. Curve balls and knuckleballs use lift forces. So what are these and how are they created?
I need an answer for this question please.

On my worksheet these are listed as one problem stating that these build off of each other. 1.) A model rocket is launched straight upward with an initial speed of 54.8 m/s. It accelerates with a constant upward acceleration of 2.07 m/s^2 until its engines stop at an altitude of 153 m. What is the maximum height reached by the rocket? How long after lift off does the rocket reach its maximum height? How long is the rocket in the...

I need a short answer for each question please.
Question 8: Water lilies, like the name implies, live in water, like ponds. They are flowering plants that make seeds, so are part of the land plant group. How can this be? Question 9: Consider the bryophyte life cycle. How is a sporophyte formed? Question 10: Some seeds can exist in a dry state for a very long time, seemingly not even alive, but then germinate when conditions are right. How...

In our experiment we used a block with different materials on its sides. One side was wood, the other was felt, the last was cork. We then used attached a string to the block and put that over a levey. At the end of it was a hanging mass. The mass of the block mentioned in the questions below is in reference to the mass of the block on the horizontal surface (not the hanging mass) Please answer the questions...
