The main difference between the internal combustion engine and the diesel engine is that the diesel engine a. does not utilize pistons. b. does not have a crankshaft. c. has no ignition system. d. has no connecting rods.

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

One object has a mass of 1 kg and another object has a mass of 3 kg. if the speeds are the same, which of the following is true about their kinetic energy?

How is zig zagging a form of acceleration?
