ROTATIONAL MOTION Quiz

• Air resistance balances the explosion forces
• The fragments are too small to alter the path
• Internal forces increase the speed of the center of mass
• The only external force, gravity, remains unchanged before and after the explosion

• Accelerated motion
• Oscillatory motion
• Circular motion
• Uniform motion in a straight line

• All particles are at rest
• Only one particle moves
• External forces are present
• Total initial momentum is zero and no external force acts

• All pieces fall straight down
• Pieces move in random paths only
• The explosion stops all motion
• The center of mass continues on the original path

• Twice the individual momentum
• Half the individual momentum
• Equal to one particle's momentum
• Zero
