The earth is rotating on its axis. it will continue to rotate unless acted upon by an outside force. this is an example of newton's first law of motion second law of motion third law of motion

For a particular reaction, ? h = -144.6 kj and ? s = -301.2 j/k. calculate ? g for this reaction at 298 k.

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative

Afeather of mass 0.001 kg falls from a height of 2 m. under realistic conditions, it experiences air resistance. based on what you know about friction, what can you say about the kinetic energy of the feather as it reaches the ground? acceleration due to gravity is g = 9.8 m/s2. a. ke < 0.0196 j b. ke = 00196 j c. je = 0 j d. ke > 0.0196 j
