If a ball is thrown straight up into the air, when will it have the most kinetic energy?"
At the top of its arc
When It lands,
When it hits the ground
Right after release

Avalue that describes how heavy an object is and is related to the force of gravity is

A30 kg weight lies on top of a massless piston of area a = 0.01 m2 the exterior air is at a (constant) p =1 atm and t = 27 c. the interior gas is 0.4 moles of (ideal) n2 and it has initial temperature 27.00 degrees c. 1. what is the initial pressure in the interior? a. 29.4 kpa b. 130.7 kpa c. 101.3 kpa the next three questions concern what happens when an amount of heat q is slowly added to the interior, raising the piston by 1 mm and raising the interior temperature to 27.40 c

Blank liquids and gases exert a buoyant force on objects placed in them
