Practice AP Physics C: Mechanics Uniform Circular Motion and Gravitation in the app →Linear momentum is the product of a system's mass and its:The SI unit for momentum is:A 110 kg football player runs at 8.00 m/s. His momentum is:A 0.410 kg football thrown at 25.0 m/s has momentum of about:Although the ball is faster, the player has far more momentum because of his much greater:Momentum form of Newton's second law is useful for systems whose mass changes, such as:Venus Williams's 2007 serve reached a ball speed of:The average force on the 0.057 kg ball in contact with the racquet for 5.0 ms was about:The quantity average net force multiplied by the time it acts is called:Airbags reduce injury by making the stopping force act over a:Deaths in car racing fell sharply when rigid frames were replaced by parts that:Rolling on the ground after a jump protects your bones by extending the:On a force-versus-time graph, the area under the curve equals the:When a football player hits a goalpost, momentum is still conserved because the Earth also:An isolated system is one for which the net external force is:Squids propel themselves like jellyfish and typically move at:A collision that conserves internal kinetic energy is called:Truly elastic collisions are achieved only with:A 0.500 kg object at 4.00 m/s hits a 3.50 kg object at rest elastically. The small object:A collision in which the objects stick together is called:A 70.0 kg goalie at rest catches a 0.150 kg puck moving at 35.0 m/s. His recoil velocity is:Why does a heavier tennis racquet have the advantage? In a collision what is conserved is:
