Gravity is the only one that is not a conservative force and does not have a form of potential energy connected with it. The statement that is true about kinetic energy but not necessarily true about potential energy is that kinetic energy depends on position whereas potential energy does not.

Why are understandings of patterns so important to human development?
andrew11 [14]
Patterns provide a sense of order in what might otherwise appear chaotic. Researchers have found that understanding and being able to identify recurring patterns allow us to make educated guesses, assumptions, and hypothesis; it helps us develop important skills of critical thinking and logic

A 1.5 kg ball is thrown upward at 10 m/s. What is its velocity when it is 2 m above the release point?
Anestetic [448]

Answer:

7.75m/s or 2\sqrt{15}m/s

Explanation:

m = 1.5kg

u= 10m/s

s = 2m

a = 10m/s^{2}

v = ?

acceleration due to gravity is negative when an object is going up because the force of gravity reduces the speed of the object

using the formula ;

v^{2} = u^{2} - 2as since the object is moving upwards (negative acceleration)

= 100 - 2(10)(2)

100 - 40

v^{2} = 60

v = \sqrt{60}

= 7.75m/s
